BlockBuster Survey 2016

Lower Hudson PRISM 2016 Block Buster Survey


The BlockBuster Survey program detects emerging invasive species introductions and fills data gaps in the Lower Hudson region. The Lower Hudson Valley counties have been divided into 5km by 5km (about 3 x 3 mile) blocks, which volunteers will select to survey.



Training sessions for Terrestrial species surveys have completed for this year. Email us at if you'd like to be on the list to get notified when we start next year's BlockBuster survey. You are welcome to self-study the materials below and select a block to survey this year if you feel comfortable. Let us know what block you would like to work in.

For aquatic species surveys, see AIS training events posted on our Events calendar.
