Always make sure you have permission to access the area you want to survey!
It is your responsibility to follow local laws and regulations. While you should try to survey all the different types of habitat in a block, this is not permission to trespass. Survey on public land first and then ask landowners for access if you cannot access all habitat types. We provide letters to help you introduce the project to landowners and a thank you letter to share your sightings should you gain access.
There is no single map layer that covers all of New York and indicates public access. However, there are a few tools that will help you determine what lands are public and for which lands you need to request permission.
- LandGrid Map & Survey Property (free app with tax parcel ownership)
- OnX (paid app with property boundaries)
