observations of anglers, other recreational users, and the public are extremely valuable. DEP cannot be everywhere, so they rely on the public to help them be their eyes and ears and report any suspicious or out of the ordinary observations. Having information such as this may allow DEP time to implement strategies to preserve our shared resources and help protect the water supply. https://www.catskillinvasives.com/blog/2025/6/30/partnerships-in-action-forest-regeneration-strategies-at-ashokan monthly 0.5 2025-06-30 https://www.catskillinvasives.com/blog/2023/5/15/crisp-on-the-front-lines-invasive-species-emerging-in-the-catskills monthly 0.5 2023-05-15 https://www.catskillinvasives.com/blog/2023/3/1/what-do-chilean-sea-bass-orange-roughy-and-copi-have-in-common-its-all-in-the-name monthly 0.5 2023-03-01 https://www.catskillinvasives.com/blog/2022/4/5/crisp-is-now-hiring-invasive-species-strike-team-technicians-for-the-2022-field-season monthly 0.5 2023-01-19 https://images.squarespace-cdn.com/content/v1/5c3e12ca3917ee893d44c40f/1649171714231-YXY1LYXBQKIZL5RB80WB/Knotweed+Stands.JPG Blog -

butterflies and other native insects love native plants. Many of these species have co-evolved over millions of years and depend on a variety of native NY plants to flourish. Monarch butterflies (Danaus plexippus) depend on native milkweed species to lay their eggs and feed their caterpillars. Invasive look-a-like plants like black and pale swallow-wort can trick monarchs into laying their eggs on them where the caterpillars cannot survive. There are over a dozen species of milkweed native to NY and most can be found in the Catskills. Species such as common milkweed (Asclepias syriaca), swamp milkweed (Asclepias incarnata), and clasping milkweed (Asclepias amplexicaulis) make for a great addition to native gardens. Milkweeds display beautiful clusters of flowers in white, pink, purple, and every color in between each summer, attracting and sustaining native butterflies, bees, and other insects. https://images.squarespace-cdn.com/content/v1/5c3e12ca3917ee893d44c40f/1c0b05de-d432-46f3-9f97-49fb54acd273/Flying+Trillium+Butterfly-Border+Garden.jpg Plant Native! - Busy as a Native Bee Did you know there are over 450 species of bees found in NY? Furthermore, only about 20% of native bee species are the hive-dwelling, eusocial bees most people think of. The remaining 80% of bee species are solitary, inhabiting hollow stems, underground burrows, and other pre-existing cavities. According to the Empire State Native Pollinator Survey, approximately 38% to 60% of native pollinator species are vulnerable to extirpation (extinction on a localized scale) due to climate change, invasive species, pesticides, and habitat loss and fragmentation. Give our native bees and other pollinator species a helping hand by planting native and incorporating habitats for native pollinators! https://www.catskillinvasives.com/privacy-policy daily 0.75 2019-01-15 https://www.catskillinvasives.com/contact daily 0.75 2026-01-21 https://www.catskillinvasives.com/subscribe daily 0.75 2019-01-21 https://images.squarespace-cdn.com/content/v1/57d6c55a2994cab476e9fb40/1473889415953-1MMODH0781V9GG0W5XV2/16.jpg Subscribe https://www.catskillinvasives.com/get-involved daily 0.75 2019-02-01 https://www.catskillinvasives.com/events-summary daily 0.75 2019-01-24 https://www.catskillinvasives.com/partners daily 0.75 2026-04-03 https://www.catskillinvasives.com/job-openings daily 0.75 2026-01-27 https://images.squarespace-cdn.com/content/v1/5c3e12ca3917ee893d44c40f/1649173786114-E37QLCXPQ7HWLZDB6NVD/EWM+at+Mohican+Lake+1July2021.jpg Job Openings https://www.catskillinvasives.com/what-are-invasive-species daily 0.75 2022-11-14 https://images.squarespace-cdn.com/content/v1/5c3e12ca3917ee893d44c40f/1649797254215-ZCD7A61902LW3YAP0N3J/unsplash-image-vFqlAJb7H6Q.jpg What Are Invasive Species? https://images.squarespace-cdn.com/content/v1/5c3e12ca3917ee893d44c40f/60992d3b-9e91-41c9-980e-f690d8682be6/Owego+Hydrilla.jpg What Are Invasive Species? Recent research in the Southern U.S. has found a correlation between invasive Hydrilla verticillata infestations and increases in Harmful Algae Blooms (HAB). HABs can cause a variety of health hazards for wildlife, pets, and humans and have been increasing in frequency throughout the U.S. in recent years. If you suspect a harmful algal bloom, report it here! https://images.squarespace-cdn.com/content/v1/5c3e12ca3917ee893d44c40f/744e38f0-6d41-4b06-b220-5233e98bd464/Giant+Hogweed.jpg What Are Invasive Species? Giant Hogweed (Heracleum mantegazzianum) produces caustic chemicals that react to sunlight and moisture. Simply brushing up against the large plant can cause severe burns, scarring, and even blindness. https://images.squarespace-cdn.com/content/v1/5c3e12ca3917ee893d44c40f/1649796574335-O3WF2C7GYS27A9SZHH4J/unsplash-image-oSaq0J4zGE0.jpg What Are Invasive Species? Feral swine (Eurasian boar, Sus scrofa) are large, aggressive animals capable of causing harm to pets and humans.

The management goal is containment unless particularly effective control methods or adequate funding sources become available. The IPMDAT Tool should be used to assess individual populations for management. https://images.squarespace-cdn.com/content/v1/5c3e12ca3917ee893d44c40f/664c11dc-6eb3-4361-ad8d-6ecb290eae8b/Knotweed+Stands.jpg CRISP Tiers - Tier 4 - Local Control Tier 4 species are too high in abundance for eradication on a regional scale to be likely even with outside funding sources. Management strategy for Tier 4 species is long-term localized suppression or containment.
