RICHARD “RANDY” STECHERT*Note: Many people are accessing this page after doing a search on known rattlesnake dens in various states.  Please be advised that it is illegal to publicly disclose den locations for this protected species, and that therefore no such information can be found on the internet. We have access to this information as professionals, and we would be happy to otherwise provide assistance on determining whether a particular property provides habitat for timber rattlesnakes. Contact us for more information.*

With 48 years of experience in studying reptiles and amphibians, Randy Stechert has conducted thousands of surveys for timber rattlesnakes, bog turtles, and other species in New York, New Jersey, and Pennsylvania. He has been called one of the leading authorities in New York State, and is often called upon by both the NYSDEC and the Pennsylvania Fish and Boat Commission to lend his expertise, especially in working with timber rattlesnakes and in protecting their habitat. He is responsible for timber rattlesnake surveys on some of the largest and most significant land holdings in the region, including West Point Military Reservation, Picattiny Arsenal, and Sterling Forest.  Statewide, Mr. Stechert is credited with determining the location of 82% of all known timber rattlesnake dens in New York.
