Bad Seeds. Part 2

high in the san gabriel mountains of the sierra madre stored files there wasn't a big sant and canyon for more than a century people have come to this secluded spot to escape the city biologist making long hike here in the nineteen sixties just felt like a really good you know while you're going to parties jump off of office these days though it's hardly wild alters and sycamore still shape a stream of very few orange leopard lilies persist they glowed like paper lanterns amidst the vast green shroud of a common garden english ivy wong returned to the canyon recently with native plant expert with the iv has grown up in these trees to finding well i'll follow through thoughtfully and family down there because somebody has been cutting it stands for basically played for eventually healed by being overtaken then shaded out by the it was the reason land here planted the id decades ago their efforts to control it have

largely failed the id has choked out most of the native plants english ivy is only one of about two dozen invasive garden plants threatening california's native plants and animals what's most frustrating to conservationist is that many of these and bases are sold in our local nurseries ruby dee is with the watershed counsel our state our cultural agency and regulates leaves that are primarily agricultural pests is wildly and weeds are now on the radar and those movements to ban some of them from the trade but we're still probably a few years away from oregon recently and english it california law actually precludes barrel plant sold a new trees and the state's conservationists are so wary of alienating california's large horticultural industry most are pushing to change the law doug johnson heads the california invasive plant council an advantage strapped public budget no kind of our home for the regulation if you can't tell the

gardens where is there the happy medium the train like a boat can be planted in areas in these highly populated areas where they will never have the opportunity to become invasive drew reidy of the watershed council doubts that approach will work he estimates about five million california homes are within a few miles of the wildland report card with the iv is the berries will travel as far as a bird well so a very urban glancing of it could get established miles away from the source meanwhile invasive plants remain on sale lead nurturing is a group of growers and conservationist has taken one step to address the problem it's produced a website and brochures that profiled the role plants and recommend alternatives that don't damage wild lands in the san gabriel mountains also said seal at nine point three ep cc
