Ash Tree Species Face Extinction

Posted on: September 15th, 2017 by Leslie_Zucker

North America’s most wide­spread and valu­able ash tree species are on the brink of extinc­tion due to the inva­sive bee­tle Emer­ald Ash Bor­er dec­i­mat­ing their pop­u­la­tions. Five of the six most promi­nent ash tree species in North Amer­i­ca were added to the IUCN Red List as Crit­i­cal­ly Endan­gered – only one step from going extinct – with the sixth species assessed as Endan­gered. One of the species, the once-plen­ti­ful White Ash (Frax­i­nus amer­i­cana) is a canopy species found in flood­plain forests of the Ashokan water­shed. Anoth­er species on the list – Green Ash (Frax­i­nus penn­syl­van­i­ca) is also found in the water­shed’s Hem­lock-North­ern Hard­wood forests accord­ing to a 2012 sur­vey by the NY Nat­ur­al Her­itage Program.

The AWSMP can help stream­side landown­ers with select­ing native species to replace dead or dying ash trees in stream­side areas. Call the Catskill Streams Buffer Ini­tia­tive at (845) 688‑3047 x6 for advise and assistance.
