  • The mission of The Nature Conservancy is to conserve the lands and waters on which all life depends

    How do we achieve this mission?

    The Nature Conservancy is working to boldly address the biodiversity and climate crises this decade. We must make a lasting difference by 2030 so people and the planet can have a brighter future. TNC has a long history of protecting lands, rivers, lakes and oceans through projects on the ground. We also collaborate with partner organizations in the field and with governments and other influencers to inform policy decisions and direct public funding to further our mission. The list of countries in which we work reflects the diverse ways in which we impact conservation around the world.

    That’s how The Nature Conservancy has done more than anyone else to advance conservation around the world since our founding in 1951.

  • The Nature Conservancy's financial information can be found here. This includes past and present annual reports, our charitable solicitation disclosure and other documentation.

  • For more information on how The Nature Conservancy is funded and uses its resources, please view our most recent annual report.

  • The Nature Conservancy creates a calendar every year and sends them to many of our members and prospective members. They are also available on request from our Member Care Center; just give us a call at 1-800-628-6860 or send us an email.

    Donations are not required, but please keep in mind that we are a non-profit group and calendar quantities are limited.

Photo & Video:

  • For the most part, The Nature Conservancy does not own the rights to the photography we use in our publications. We have permission to use the photos for specific situations, often for one-time use in our magazine. If you would like permission to use a photo you've seen on our web site or in one of our publications, please contact the photographer directly.

  • Due to limited resources and an overwhelming level of interest, we are no longer issuing photographer's guidelines and are unable to accept unsolicited photography submissions. This includes Nature Conservancy magazine as well as other Conservancy publications.

    The only unsolicited materials we can accept are emails featuring a link to your personal web site or online portfolio. Please send such emails to photo@tnc.org, and include a list of any Nature Conservancy areas that you have already photographed. We will review these links on a periodic basis and will contact you if your work matches our project needs. Please do not send unsolicited emails with attachments.

    Feel free to contact The Nature Conservancy's local, state and country offices in areas where you have photographed and/or may be planning to visit. These individual offices may have photo acquisition needs, contests, products, etc., which may be of interest to you.

  • The Nature Conservancy's Tax ID Number (Employer Identification Number) is 53-0242652.

  • We will be happy to send a replacement acknowledgement for your donation. Please contact the Member Care Center by phone at 1-800-628-6860, or email member@tnc.org.

  • You are always welcome to designate your donation to the area or project of your choice. Simply send us a note with your donation by mail, letting us know where you would like your donation to be used. We will make sure it is allocated to the right project, and send you an acknowledgement to that effect.

    If you are donating by phone, just tell the Member Care Professional who takes your donation that you would like to earmark it for a particular project.

    You can also donate online. Please note that donations using that form do not renew memberships, and that allocation is limited to states or countries rather than individual projects.

  • The Nature Conservancy is a 501(c)3 organization, and donations are tax-deductible. The amount of the gift that is eligible for deduction can depend on several factors, including the size and nature of the donation.

    The Nature Conservancy does not provide legal, tax or accounting advice. You are encouraged to consult your own professional advisors on tax matters.

    The Nature Conservancy's tax ID number (EIN) is 53-0242652.

  • There are many ways you can give to The Nature Conservancy. 

    • To donate by mail, please send your check or money order, payable to The Nature Conservancy, to:

      The Nature Conservancy
      Attn: Treasury
      4245 N. Fairfax Drive, Suite 100
      Arlington, VA 22203-1606
      (Include a note if you would like the donation to be used for a particular project or chapter.)
    • To donate by phone using your credit card, please call our Member Care Center, toll-free, at (800) 628-6860.
    • You can donate online using our secure online donation form. 
    • To contact our Estate Planning team for information on stock gifts, annuities, wills, and other ways of giving, please write to legacy@tnc.org or call (877) 812-3698.
  • The Conservancy accepts a variety of non-cash gifts, including goods and services, from its generous supporters. There are three types of contributed goods, including:

    1. Tangible personal property gifts. These are gifts that The Nature Conservancy intends to sell (e.g., a piece of jewelry from an estate).
    2. In-kind goods. These are goods that the Conservancy intends to use. An example would be a donated truck that could be used at a preserve site or lumber that is used to build a shelter.
    3. In-kind services. These are professional services that are donated to the Conservancy, such as pro bono legal services.

    If you would like to contribute goods or services to the Conservancy, please contact your local office for more information.

  • The Conservancy uses a centralized bank (called a "lockbox") to coordinate the processing of gifts and donations we receive from our members nationwide. This strategy saves costs and increases efficiency, maximizing the amount of the donor's gift that goes towards our vital work; it would be impossible to process all of the mail through our physical headquarters in Arlington, Virginia.

    While the gifts are entered in one place, the lockbox does not affect where a donor's gift is designated. We always honor a donor's wishes concerning the specific programs or projects he or she would like to support and the lockbox helps facilitate our efforts to carry out our donors' intent.

Tribute Giving:

  • You can give a gift membership online, by phone, or by mail.

    To donate by phone, please contact our Member Care Team toll-free at 1 (800) 628-6860.

Workplace Giving:

  • Your employer’s match – or your gift through your workplace – helps save all that nature gives us. Find out more on our Workplace Giving page.

  • Donations through your workplace do qualify for membership and the magazine, but we often receive lists of donors from employers after we receive the donations. Payroll deduction checks are usually sent to us in lump sums, and we receive the lists of donors later.

    To ensure your membership is properly credited right away, we suggest that you:

    1. Fill out your company's payroll deduction pledge form;
    2. Email a copy to workplacegiving@tnc.org, or:
    3. Mail us a copy at 4245 N. Fairfax Drive, Suite 100, Arlington VA 22203-1606.

    We can update your membership each year as soon as you've made the pledge.

    If you have further questions, please email us.

Giving Online:

  • Because the Address Verification System is an automated system that relies on the exact match up of address data, records that are entered in different formats can sometimes interfere with credit card processing. For example, some companies do not follow a standard procedure for entering P.O. Box numbers, so online donors with P.O. addresses are more likely to experience problems. If you reverse the format of the address line (e.g., enter in the address 1234 P.O. Box rather than P.O. Box 1234), you may be able to resolve the problem. Donors with international addresses may also run into authentication issues.

    If you run into difficulties with the online form, the Conservancy's Member Care Team can always process your credit card donation over the phone or by mail. Please call us toll-free at (800) 628-6860 for assistance and more information.

Thank You Gifts:

  • Gift items are usually shipped at the non-profit rate (third-class). They can take up to six to eight weeks to arrive. If it has been more than eight weeks since your donation was processed, and you still have not received your gift item, please contact the Member Care Center toll-free at 1-800-628-6860 or at member@tnc.org.

  • If your gift was damaged, lost, or stolen before it reached you, just let us know and we will be happy to send a replacement. Contact the Member Care Center by phone at 1-800-628-6860 or email us

  • If you received the wrong gift item as a thank-you for your donation, just let us know and we will be happy to send the correct item. Contact the Member Care Center by phone at 1-800-628-6860 or email us

Real Estate:

  • Yes, the Conservancy is pleased to accept two types of land: natural areas that become preserves, and trade lands (lands not meeting our conservation criteria, that are given to us with permission from the donors to sell them to acquire other conservation properties). Both types of land gifts are critically important to the Conservancy's mission.

    For information about selling or donating a natural area, please contact our local office in the state where the property is located. For information about donating trade lands, please call the Worldwide Office toll-free at (877) 812-3698.

    In addition to outright donation and protection, there are many options for landowners who want to work with The Nature Conservancy. We recommend you speak with the Conservancy office in your state.

Recurring Gifts:

  • Yes, you can! By joining our Conservation Champions program, you can arrange to have a donation taken each month automatically from your checking account or credit card. The Conservation Champions program accepts Visa, MasterCard, and American Express. Your financial information will always be kept confidential.

    You can make a monthly gift online or call us at 1 (800) 628-6860 to set up the automatic donations over the phone.

  • To make a change to your Conservation Champions automatic donations, please call the Member Care Center at 1 (800) 628-6860 or send us the new information by to:

    Worldwide Office
    The Nature Conservancy
    4245 North Fairfax Drive, Suite 100
    Arlington, VA 22203-1606

    We will need:

    • your name and address
    • the old information for the automatic debits
    • the new information


  • If you would like to cancel your automatic donations with our Conservation Champions program, please give us a call in the Member Care Center at 1 (800) 628-6860. We will cancel the donations immediately.

  • Yes, you can. By joining our Conservation Champions program, you can have your regular, automated donations applied to our special membership program and receive fewer mailings each year. You will receive a pledge statement at the beginning of each month to help you keep track of how your gifts are helping conservation around the world.

    Ask your bill-pay service to send your donations to The Nature Conservancy, Attn: Treasury; 4245 N. Fairfax Drive, Suite 100; Arlington, VA 22203-1606, and include your membership number. Let us know when you start making donations this way and we will be sure to apply the Monthly Giving indicator on your membership record.

    In addition to checking accounts, the Conservation Champions program accepts Visa, MasterCard, and American Express, and your financial information will always be kept confidential.


  • Many of our mailings are prepared weeks in advance, and some members receive a renewal notice after they have already sent their donation. If you made your donation within the last six weeks, and received an acknowledgement along with an updated membership card, your membership has been renewed.

    If you made your donation more than six weeks ago, and have not received an updated membership card, please contact our Member Care Center by phone at 1(800) 628-6860 or by email. Our Member Care Professionals will be happy to research the problem and get back to you promptly.



  • You can change your address by contacting Member Care. 

    Because many of our mailings are prepared in advance, we ask that you allow a few weeks before the change takes full effect.

  • If you are not a member of The Nature Conservancy, and you are receiving invitations to join, it's likely that another organization has shared your name and address with us. If you would like to be removed from our mailing list, please call our Member Care Center at 1(800) 628-6860 or email us.

    We will need the following information in order to make sure you are removed from the list:

    • Your name and address exactly as they appear on the mailing
    • The mailing code, which begins with the letters AHOMQ. (In some cases, that code can help us pinpoint where we received the name.)

    Please note that because many of our mailings are prepared in advance, it might take some time before the change takes full effect. We appreciate your patience and will do everything we can to expedite the process.

  • If you are a member and would like to cancel your membership with The Nature Conservancy, please call our Member Care Center at 1(800) 628-6860, or email us. Please let us know why you would like to cancel, as it can help us improve the membership experience for our donors.

    If you would simply like to receive less mail, we will be happy to tailor your membership to your wishes. Your Member Care representative can discuss the options with you. 

    We can also stop the magazine from being sent if you would prefer not to receive it.

    Just let us know what suits you best, and we will take care of it right away.

  • If you are a member and you would like to receive less mail, we will be happy to tailor your membership to your wishes. Just let us know which works best for you, and we will take care of it right away. You can call our Member Care Center at 1(800) 628-6860, or email us.


  • If you would like someone else's name removed from our mailing list, please contact our Member Care Center by phone at 1(800) 628-6860, or email us. We will need the following information:

    • The name and address as they appear on the mailing;
    • Membership number (if applicable);
    • Mailing code (if applicable) that begins with AHOMQ.

    We will remove the name as quickly as possible, but because many of our mailings are prepared weeks in advance, it could be several weeks before the change takes full effect.

  • We try to avoid creating duplicate memberships whenever possible, but it happens every now and then. Duplicate memberships can be created for many reasons, including:

    • Donation with change of name
    • Donation with change of address
    • Spouses making donations separately

    If you are receiving two copies of our mailings (particularly the magazine), please let us know as soon as possible either by phone (800-628-6860) or via email. We can merge your duplicate memberships permanently in our system, resulting in just one record that contains your entire history with The Nature Conservancy.

    To merge your memberships, we will need the following information:

    • Name(s)
    • Address(es)
    • Membership numbers (if possible)
    • Preferred information (how you would like the membership to be addressed)

    Because many mailings are prepared several weeks in advance, it may take a few weeks before the update of your membership is fully implemented. In the meantime, consider passing the extra information along to others who might be interested.

    If you have recently joined The Nature Conservancy but are still receiving invitations, please allow a few weeks for the original list to be updated and your name removed from further invitations.


  • You can join The Nature Conservancy by making a donation by mail, by phone, or online.

    • To join by phone: 
      Please call our Member Care Center, toll-free, at 1-800-628-6860 to donate by credit card.

  • Although we make every effort to avoid duplications, this cross-checking of potential membership lists is not always fool-proof. Any variation in name or address could prevent us from identifying the duplicate record.

    If you are a member and receive another invitation to join The Nature Conservancy, please indicate this on the membership application that has your name and address on it and return it in the envelope provided.

    If you have recently joined the Conservancy, the invitations to join are from the same list to which you first responded; please allow a few weeks for the list to be updated and your name removed from further invitations to join.

    You can also call the Member Care Center toll-free at 1-800-628-6860, or email us. Please allow 6 - 8 weeks for the corrections to be implemented.

  • After your donation is received and processed in our system, it can take up to three weeks for your membership card to reach you by mail.

    If you made your donation more than three weeks ago and have not yet received your membership card, please contact the Member Care Center by phone at 1-800-628-6860.

    If you are expecting a gift item, please look for it under separate cover from the acknowledgement letter, and allow up to eight weeks for it to arrive.

  • If you would prefer not to receive The Nature Conservancy's publication, we will be happy to edit your membership to your liking. Please email us with your request, and we will take care of it right away.

    Please bear in mind that the mailing list for the magazine is printed some time in advance, so it's possible that another issue will arrive after we receive your request.

  • Please contact the chapter office in the state in which the preserve is located.

  • We have over 400 preserves in the United States alone, which can be found on our chapter websites. 

  • Our primary focus has always been to protect the entire spectrum of native biological diversity. In North America, hunting and fishing are only permitted on a Conservancy preserve in instances where these activities are compatible with achieving the site’s written conservation goals.

    The most common reason for allowing hunting and/or fishing on Conservancy preserves is to maintain or restore the integrity of sensitive species and biological communities. Another common reason the Conservancy allows hunting and/or fishing on some of our preserves is to respect the practices and cultural traditions of human communities. In some situations, we are motivated to open a preserve to hunting for both reasons: ecological and cultural. We do not permit hunting on those lands we own and manage where hunting may generate collateral threats, or detract from our ability to achieve our conservation goals.

    For more information, please refer to this Conservancy fact sheet on hunting and fishing in North America.

    If you would like to know whether hunting or fishing is allowed on a particular preserve, please contact the chapter office in the state in which the preserve is located.

  • In many places, managed hunting is a critical tool to reduce wildlife game populations that have grown beyond the habitat’s ability to support them. Managed hunting is a carefully regulated action implemented to protect the ecological integrity of sensitive species and biological communities. At many of our sites, populations of non-native animals like feral hogs and of native animals like white-tailed deer can grow well beyond the ability of the natural communities to withstand their effects. In those situations, we may employ carefully managed hunting as a tool to reduce populations in order to reduce the damage that they cause, allowing natural communities to recover their full vigor and diversity.

    To take one example, white-tailed deer have increased dramatically across North America in recent decades. Multiple factors have led to larger deer herds including land use changes (e.g., increased suburbanization), a concerted effort by state wildlife agencies to increase recreational hunting opportunities, declining numbers of hunters with limited access to hunting lands and a decline in natural predators.

    Deer are a natural, native component of our ecosystems. But with unchecked growth in deer populations, many areas are over-run with deer, causing well-documented negative impacts on habitats. Chronic overbrowsing greatly reduces the diversity of forest plants, stunts growth and leads to failures in tree reproduction. Further, deer can play a role in the spread and proliferation of invasive plants and are linked to the decline of some bird populations. The effects of excessive deer browsing on habitats can last decades, impacting not only today’s forests but also future forests. Elevated deer populations also have consequences for public safety (e.g., traffic accidents), human health (e.g. Lyme disease) and the deer themselves (e.g., spread of diseases such as Chronic Wasting Disease).

    Managed hunting on our preserves helps reduce these impacts, allowing natural communities to recover their vigor and diversity. Practices vary across the Conservancy from state to state and country to country. In all cases, managed hunts on Conservancy lands are conducted to meet the dual goals of healthy habitats and wildlife populations.

Visiting a Preserve:

  • To get the most from your trip, and to protect yourself from the elements, you may want to include the following items in your backpack:

    • Binoculars
    • Camera

Our intention is to provide an informative tool for those interested in conservation and as a means of allowing our members and the public to become more involved in our mission. We recognize that visitors to our web site may be concerned about the information that they provide to us and how we treat that information. The Nature Conservancy is committed to honoring our constituents' privacy preferences.

    To this end, the Conservancy supports the following principles:

    Consumer Choice
    We believe that a visitor to our web site is the one to best determine:

    • When—and under what conditions—to provide "personally identifiable information" (e.g., data that may be used to identify, contact, or locate a person)
    • When such information may be shared with other organizations
    • When to remain anonymous

    Informed Consent
    When personally identifiable information is collected, we believe that a visitor to our web site has the right to:

    • Know when we are collecting personal information
    • Know what personal information is collected, and the purpose of any such collection
    • Expect the opportunity to choose whether or not personal information will be provided to any third parties
    • Expect reasonable steps to be taken to protect personal information from unauthorized use
    • Review the accuracy of personal information and update it
  • All sensitive information (such as your credit card information) provided to The Nature Conservancy or our trusted partner, Convio, is transmitted using Secure Socket Layer (SSL) encryption. SSL is a proven coding system that lets your browser automatically encrypt, or scramble, data before you send it to us. We also protect account information by placing it on a secure portion of our web site that is only accessible by certain qualified employees of The Nature Conservancy.

    Unfortunately, no data transmission over the Internet can ever be 100% secure. While we strive to protect your information to the fullest extent, we cannot ensure or completely guarantee the security of such information.

    The VeriSign Secured Seal
    The globally recognized VeriSign Secured Seal (at right) allows you to learn more about the web sites that you visit before you submit any confidential information. The Nature Conservancy’s and Convio’s investment in this advanced technology ensures that the web page you are visiting is authentic, secure, and that any data or information you submit will be protected by 128-bit SSL encryption.

    Whenever you see the VeriSign Secured Seal on our web sites, you can personally verify that the web page in question is both secure and administered directly by The Nature Conservancy or Convio. You may submit personally identifiable information and/or sensitive data (such as credit card numbers) to the web site with the assurance that:

    • The web site has a VeriSign Secure Server ID
    • VeriSign has verified the organizational name and that The Nature Conservancy and/or Convio have the proof of right to use it
    • The web site legitimately runs under the auspices of The Nature Conservancy and/or Convio
    • All information sent to the web site, if in an SSL session, is encrypted, protecting against disclosure to third parties
