Fort Drum – Cantonment Area Herbicide Application

Adirondack Research implemented a large-scale understory invasive species management program across the cantonment area of Fort Drum, treating approximately 64 acres across multiple Invasive Management Areas (IMAs). The project focused on reducing dense invasive shrub layers to support native regeneration, improve forest structure, and enhance habitat conditions within highly managed landscapes. Design map to emphasize treatment intensity, spatial coverage, and operational...

Fort Drum Beech Control – Hack-and-Squirt Herbicide Treatment

American beech (Fagus grandifolia) can become an undesirable species in managed forest systems when it forms dense understory thickets that suppress regeneration of desired tree species. At Fort Drum, this condition is common in previously harvested areas, where beech root sprouting has resulted in high-density regeneration that limits forest diversity and habitat quality. In 2025, Adirondack Research partnered with Atlas Contracting...

We contracted with Adirondack Research ad Consulting to coordinate our pheromone trapping program in Worcester, MA. Ezra Schwartzberg lead the effort and did an amazing job. The season’s trapping program went flawless, and his organization and management skills made our life A LOT easier. We were very impressed with his coordination with our lab, facilitating sample analysis, trapping logistics, and reporting. He also contributed a great deal to helping us calibrate our in-field volatile release rate. Adirondack Research and Consulting offers a great service and handles complicated survey methods with ease, professionalism, and timeliness. Very easy to communicate with too.

Ezra Schwartzberg helped with design, implementation, and management of the biological research infrastructure at Intervale Lowlands Preserve in Lake Placid, NY. We needed someone with broad expertise to advise on a long-term project with detailed scientific objectives as well as with many open-ended questions relating to climate change monitoring and management on private lands. Ezra was able to provide us with planning to facilitate our goals. We’re very impressed with his use of social media, smartphone apps, and crowdsourcing to make the data we collect useful to a broad audience.

Intervale Lowlands Preserve
Ezra completed a large set of assessments for us in a very short period of time. He was able to work with his team with short notice under pressing timelines as we were preparing to meet legislative deadlines. His work came in complete, at a very high quality, and provided us with the information we needed. He was also willing to accommodate a changing work-plan, which was very beneficial to us.

The Importance of Accessible Design Standards for Interpretation and Cartography

By: Olivia Otsuka Approximately 36 million Americans have at least one disability—over 19 million have a mobility impairment, over 10 million have a hearing impairment, and about 7 million have a visual impairment (6). Individuals with disabilities are entitled to the same experiences as able-bodied individuals (7). Thus, it is of the utmost importance that cartographers and graphic designers practice universal and barrier-free design when creating maps and graphics in order to prioritize accessibility (1). To effectively practice universal design, people with disabilities need to be involved in... read more

Four Native Wetland Species Negatively Impacted by Purple Loosestrife

Purple loosestrife (Lythrum salicaria) is an invasive species that originated in Europe, Asia, and Northern Africa but has been present in the Eastern United States since 1830. Currently, it is present in the vast majority of the United States. According to New York Invasive Species Information purple loosestrife grows in meadows, wetlands, and other wet areas like ditches. Given its invasive nature, once introduced to one of these areas purple loosestrife grows rapidly and becomes the dominant species. This leads to a lack of diversity in... read more
