2
What is an invasive species?
Not native to the ecosystem Causes harm to the economy, human health, or the environment Asian Longhorned Beetle Northern Snakehead
3
Biological Characteristics of Invasive Species
Fast growth Rapid reproduction High germination rate Phenotypically plastic Environmental generalists
4
Why are invasive species a threat?
Invasive species are one of the greatest threats to New York's biodiversity and threaten many aspects of our well-being Invasive species contribute to: Habitat degradation and loss The loss of native fish, wildlife and tree species The loss of recreational opportunities and income Crop damage, forest damage, and diseases in humans and livestock
6
Promote education, prevention, early detection and control of invasive species to limit their impact on the ecosystems and economies of the Catskills.

Current Distribution

What Is At Risk for Pennsylvania?
Current Values of Some Commodities Affected Unable to Estimate Value of Losses Forest Products: $16.7 billion Grapes: $28 million Apples: $87 million Peaches: $19 million Nursery and Landscape: $944 million Property Values Tourism at PA parks and Game Lands PA Ecosystems New Business Initiatives Port of Philadelphia > Slide courtesy

What’s at Risk in NY? Forest products industry - $12.4 billion in economic output and 61,171 jobs Fruit - $400 million in economic benefits annually for New York State 2nd in Apple Production 3rd in Grape Production Property Values Tourism Ecosystems Ports Slide courtesy

Quarantine 13 county quarantine in PA Slide courtesy

Spotted Lanternfly Lifecycle One Generation Per Year
Egg Laying: September - November Adults: July - December Eggs: October - June One Generation Per Year Fourth Instar: July - September Hatch and 1st Instar: May - June Third Instar: June - July Second Instar: June - July Slide courtesy
17
Quarantine Covers all life stages and conveyances
Limits movement of commodities and home articles May allow continued interstate and international trade. Requires inspection and safe movement from the quarantine Slows processes and trade down, but does not completely stop trade Wood recycling can still be completed, but may need think about how is done Lumber harvest may still be made, but may need timelines Slide courtesy
18
Control & Monitoring Banding
4th instar and adults need Ailanthus 1st set of sticky bands very effective on 1st- 4th instars Uses known behavior of nymphs going up trees each day against the insect Target Ailanthus if they are in the area No pesticides used with tree bands Slide courtesy

Locations of Ailanthus in iMapInvasives
20
Ailanthus altissima Tree-of-Heaven
Native to China, first introduced as an urban tree in 1700’s Grows up to 60 ft tall Has allelopathic effect on nearby vegetation Chuck Bargeron, University of Georgia, bugwood.org Ecological Research Alliance
21
Ailanthus identification
Typically grows in thick clusters Large compound leaves 3 feet long with up to 40 leaflets Leaflets have small lobes at the base Crushed flowers or foliage has a strong acrid smell Arieh Tal, New England Wildflower Society Arthur Haines, New England Wildflower Society Arieh Tal, New England Wildflower Society
23
Criteria for Ranking Priority Early Detection/Rapid Response Plants
Species is capable of invading forest or riparian habitats such as those present within the CRISP PRISM Species can be spread within the region Known, problematic infestations already established within the CRISP PRISM
24
Terrestrial Plants Persicaria perfoliata Mile-a-Minute
Brachypodium sylvaticum Aralia elata Syringia reticulata Impatiens glandulifera Mile-a-Minute False Brome Japanese Angelica-tree Japanese Tree Lilac Himalayan Balsam Thomas B. Denholm, New Jersey Department of Agriculture, Bugwood.org Leslie J. Mehrhoff, University of Connecticut, Bugwood.org
25
Why is Mile-A-Minute (Persicaria perfoliate) a threat?
Rapid growth ≈ 6 in./day Vines may grow over 25 ft./yr Climbs over native plants eventually outcompeting them, leading to habitat degradation and loss Prolific seed disperser. It’s seeds are dispersed by birds, mammals and even one species of ant. Seeds remain viable for 6-7 years in the soil. It’s seeds can float and survive for 7-9 days in water, so can float downstream to invade other areas Mile-A-Minute Infestation
26
Mile-A-Minute Habitats
Prefers disturbed areas in full sunlight such as roadsides and old fields. Grows most rapidly on moist soils but tolerates extremely wet or dry soils. Mile-A-Minute Infestation
