Invasive Species Summit_11062015_Afternoon Session Current and Emerging Threats

Submitted by Jschuler on Mon, 12/07/2015 - 12:09

Moderated by: Linda Rohleder, Director of Land Stewardship and Coordinator of the Lower Hudson PRISM. In 2013, Linda received her PhD in Ecology from Rutgers University, where she studied the effects of deer on forest understories. Linda built the Trail Conference’s Invasives Strike Force volunteer program. By 2014, the program had about 200 trained invasives-mapping volunteers who collectively had surveyed more than 870 miles of trail for invasive plants. She has organized invasives-removal workdays in parks across southern New York and northern New Jersey.

Map Library: Lower Hudson PRISM: SRN Block-Buster Support Maps (air photo)

Submitted by John Mickelson on Mon, 07/06/2015 - 00:57

Following this link will take you to our Google Drive Map Library of 377 detailed air photo base map (one each for all of the Survey Reference Network blocks). Included as overlays (on the air photo base map) are Protected Areas (from the NY Protected Areas Database (PAD)) as well as wetlands from the USFWS National Wetland Inventory (NWI).  Once you have explored and selected your adopted Block, identify its alpha-numberic Label name (e.g. 5661B) and find its supporting map within this library.

Data\Map: Lower Hudson PRISM SRN Master Species List: Code Matrix

Submitted by John Mickelson on Sat, 06/13/2015 - 22:52

List of some ~500 invasive plant species, compiled from: iMap, EDDMAP and BBG\NYMF indicating the species that have been recorded in or near the Lower Hudson PRISM region (~350 have been confirmed). 

To be used as part of the July 2015 "Block-Buster" event and beyond.

Provides: Latin names, common names and USDA Symbol codes for each of the plants; apha-numberic Symbols to be used as input notatations for species found at each survey site, in the MASTERLIST Survey Form. 

MAP: Lower Hudson PRISM: Invasive Spp. Distribution Maps (examples)

Submitted by John Mickelson on Tue, 06/09/2015 - 19:39

Set of 3 maps (ea. in PDF and JPG format) depicting:

A) The LHP region (and adjacent counties) with all known invasive species occurrences (from all programs: iMapNY, EDDMAP and NYBG\NYMF)

B) The same region, illustrating the known occurrences of Japanese knotweek (from all programs)

C) The same region, illustrating the known occurrences of Japanese angelic (from all programs)

MAP: LHP SRN Block-Buster Event: Reference Maps

Submitted by John Mickelson on Mon, 06/08/2015 - 23:05

A Zip archive set of 3 maps (ea. in .JPG and .PDF format), depicting the Lower Hudson PRISM region and encompassing 5kmX5km Survey Reference grid, with block labels and backgrounds of:

1) shaded relief

2) reference base maps

3) satellite imagery

The PDF maps work well, in that they allow the user to both zoom into the digital file (maintaining a fairly high image resolution) as well as turn off the block labels, allowing for a clearer view of the contained block systems.

The New York State Hemlock Initiative

Submitted by Jschuler on Fri, 05/22/2015 - 15:42

New York State Hemlock Initiative
We recently created the New York State Hemlock Initiative
(NYSHI) to organize the state-wide efforts of multiple agencies,
volunteers, and other stakeholder groups to save our hemlocks. This
organization will work as a clearinghouse for information aboutHWA, to work on a statewide level to identify priority hemlock
stands for management, and serve as a portal to organize volunteer
detection and monitoring efforts. If you are interested in working
