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.

8. CRISP Region includes:
Otsego
Schoharie
Delaware
Greene
Ulster
Sullivan &
Orange
Major Landowners
DEC 287,500 ac.
DEP 156,824 ac.

10. Prevention Spotted Lanternfly Lycorma delicatula

11. Current Distribution

12. Spotted Lanternfly makes use of over 100 different plant species, but strongly prefers the invasive “Tree of Heaven”

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

14. 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

16. 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

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

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

19. 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

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

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

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.
