Help Save the Hemlocks! | Saturday 10/22

Sick and tired of peak bagging, leaf peeping, and red lining? Eager to try something completely different? There are still a few slots left for this Saturday’s hemlock wooly adelgid training and survey in Denning. Learn about hemlocks, their key role in Catskills ecosystems, and how the wooly adelgid has become a threat. This is a full day’s outing, with training by Dan Snider of the Catskill Region Invasive Species Partnership and then we will complete a survey of a hemlock stand. Not a long or strenuous hike, but expect to spend the day outdoors under the canopy of ancient hemlocks.

Space is limited to please register by Friday, 10/21.

Join us for a day of Invasive Species (Swallowwart) Removal

Join us Monday July 18th from 9am to 4pm for a day of invasive species control in Pine Hill.  The Primary objective is to continue to control and eradicate Swallowwart and Oriental Bittersweet from the property off of Lower Birch Road in Pine Hill, NY.

Work  can consist of scouting for plants that we’re not aware of, digging the plants that are away from the main infestations, cutting plants that have already had their flowers removed.  There will also be information for the volunteers on the life cycle and issues with the plant.  The day will be led by Andrew, a Cornell Master Naturalist,  professional horticulturist.  Trainer in the DEC WAVE program and level 7 reporter in the DEC invasive program.

All tools and equipment will be provided, participants should bring plenty of water, lunch, and sturdy hiking shoes.  Bug spray and sunscreen are always a good idea as well.

To get to the property go to Pine Hill, NY 12465 via NY route 28.  In Pine Hill access Birch Creek Road right off 28.  Take Birch Creek Road until you can take a right turn on to Lower Birch Creek Road…there will be a large open field on the right. Lower Birch Creek Road is a well maintained dirt road.  Take it to the end where there’s a DEC parking area where everyone will meet.

Identifying Hemlock Woolly Adelgid and Emerald Ash Borer | Saturday May 21st | 1-3pm

Join Dan Snider of the Catskill Center’s C.R.I.S.P. staff for a power point presentation and discussion on identifying Emerald Ash Borer and Hemlock Woolly Adelgid. The talk will include some brief life history, biocontrol info and management practices. The training includes going outdoors and offering field training in practical surveying techniques, what to look for to document extent of infestations, how to survey for biocontrols and other useful information.

Hemlock Citizen Science

CRISP will also be doing training’s for hemlock woolly adelgid identification and reporting. I will be training volunteers in HWA ID and infestation density characterization, as well as iMap Invasives use to report any instances of HWA found in hemlock stands. The goal is to help CRISP characterize the outer limits of the infestation in the Catskills. Dates of training’s TBD.

For more information or to sign up contact Dan Snider, Field Projects Manager, CRISP at

Hemlock Surveys

CRISP is doing hemlock health and regeneration surveys throughout the Catskills. I am looking to take 1 or 2 volunteers out every trip, which will include bushwacking on mountainous and difficult terrain, perhaps with stream crossings. We will be out for between 4 and 7 hours at a stretch.

You will be trained in GPS data collection, hemlock and hemlock woolly adelgid ID and survey techniques, as well as some general-purpose forest survey techniques (DBH measurements, leaf-crown ratio, etc). Dates are TBD, but would be on weekdays in summer.

BioBlitz at the Thorn Preserve in Woodstock

We’re having our second annual BioBlitz, an event where we spend a weekend sending out identification experts to categorize as many organisms on the property as possible. The end goal is to have a thorough idea of the species composition at the Thorn Preserve, and to use to the data to form a stewardship plan for the property.

We will be sending out 2-3 trained volunteers with each expert. The trained volunteers will be recording the organism’s common name, scientific name, gps location, habitat type it was found in, and some other data, taking pictures of each organism, and in general taking notes on behavior etc that the expert discusses.

We’re also looking for volunteers to direct parking, to man the refreshments table, to keep track of ID guidebooks and equipment that are lent out, and some other tasks.

We are looking for between 30 and 45 volunteers for the event, taking place from June 10th through June 11th. Our schedule for what time experts are coming will be up on our website soon. Our scheduled training days so far are Wednesday June 1st at 6 pm and Sunday June 5th at 11 am, both at the Thorn Preserve, which is located at 55 John Joy Road in Woodstock, NY.

If you cannot make the training’s, you are also welcome to come to the event and follow the experts around – this event is both for data collection and educational purposes.
