ecological planners are beginning to frame the discussion of future cities in terms of what they do have-their natural and cultural assets.
New technologies for treating wastewater for example, look less like industrial treatment plants and more like ecosystems;
and ecologists understand what kind of landscapes people want in different cities, so that future landscape designs can meet aesthetic and cultural as well as environmental needs.

Instead of battling to return ecosystems to a pre-human state, as previous efforts have tried to do,
and recognise that humans are an integral part of many ecosystems now. In many cases they argue,
we should accept ecosystems that incorporate nonnative species, value them and try to conserve them as"novel ecosystems  that are worth protecting.
Tipping point From Hawaii to the Galapagos, conservationists are beginning to accept and implement this new approach-embracing introduced species,
efforts are already being made to restore native ecosystems, or in some cases plant nonnative trees and grasses,
or introduce animals to restore the functions that the pre-human ecosystem once provided oe such as reducing soil erosion,

Ultimately, the reason for conserving tigers may be less to do with their ecosystem or tourist economy benefits,

If we want to preserve the few remaining forests and other diverse ecosystems around the world,

Ecologists Discover; Climate Change Appears to Be accelerated Driving Growth Forest in Maryland. Speed is not a word typically associated with trees;
The study offers a rare look at how an ecosystem is responding to climate change. For more than 20 years forest ecologist Geoffrey Parker has tracked the growth of 55 stands of mixed hardwood forest plots in Maryland.
The plots range in size, and some are as large as 2 acres. Parkers research is based at the Smithsonian Environmental Research center
Forest ecologists know that the trees they study will most likely outlive them. One way they compensate for this is by creating a oechronosequence a series of forests plots of the same type that are at different developmental stages.
He specializes in the data-analysis side of forest ecology. oewalking in the woods helps but so does looking at the numbers,
Ecosystem responses are one of the major uncertainties in predicting the effects of climate change. Parker thinks there is every reason to believe his study sites are representative of the Eastern deciduous forest,
the regional ecosystem that surrounds many of the population centers on the East Coast. He and Mcmahon hope other forest ecologists will examine data from their own tree censuses to help determine how widespread the phenomenon is.
