What Kind of Trees Belong in the Arroyo Seco???
5, 2004 - There
will be two opportunities for the public to learn more about an exciting
Arroyo Seco stream restoration project this week and to speak up for
native habitat. There will be
presentations about the restoration program to meetings of the the
Hahamongna Watershed Park Advisory Committee on Tuesday and the Urban
Forest Advisory Committee on Wednesday.
Arroyo Seco Stream Restoration Project will restore stream and habitat
values in the only two unchannelized areas of the Arroyo south of
Devilís Gate Dam. The first
area extends from the dam south to Brookside Golf Course; the second
extends from the
these areas have not been degraded by the massive concrete channel that
bisects the rest of the Arroyo, they still have tremendous natural values.
They are a powerful reminder of what the Arroyo once was.
They are also models of what a restored Arroyo Seco can be.
element of the program that might be controversial is the plan to remove
more than two hundred non-native trees in these two areas. A large number
of non-native trees have moved into these sensitive riparian areas to
choke out the trees and plants that are appropriate to a streamzone.
Some are invasive species that retard the growth of more valuable
natives, such as sycamores, willows and cottonwoods.
Others are just out of place in a natural streamzone.
designation of which trees will go has been prepared by landscape
architect Lynne Dwyer, who has long been involved in tree-planting and
Arroyo Restoration activities. As
executive director of North East Trees several years ago, Lynne was
instrumental in shaping the Arroyo Seco Watershed Feasibility Study, so
she has impeccable credentials to determine which trees enhance stream
values and which do not.
Arroyo Seco Stream Restoration Project will restore valuable stream
habitat in the two most sensitive areas of the Arroyo south of Hahamongna.
Enhancing habitat is a key part of all stream restoration programs.
Arroyo_Seco_News hopes that you will support the project and other
watershed restoration activities.
