Are you helping the local habitat by planting native vegetation?
My own yard is mostly native and I love it!
Answer:
It seems that you are really concerned about the habitat ecology and conservation.
On world environment day ie on 5th June 2007, we planted 200 indigenous sapling in out factory premises. we are planting trees here since last 10 years ie from the start of this facility and I would like to tell you that since last 10 years we had a green cover of indigenous plants in our premises, it really feel cool because of this green cover even in summer.
oh yeah.
out back is fully native.
in the shade, under the trees, is where the poison oak grows.
out in the full sun is where all the thistles grow.
can't get more native than that. :-(
Mostly, you have answered your own question very well! I can only add a few other pointers--it helps to prevent the eventual loss of the variety of native species by keeping a healthy diversity of ecological niches in place--instead of replacing them with invasive exotics that can eventually out-compete the locals, and destroy habit. (like has already occurred with kudsoe, English Ivy, or Mongolian blackberry.) These will eventually create a "mono-culture" which supports LESS species, and leads to extinctions, or narrowing of habitats for the other species.
This is an enormous problem in isolated environments such as Hawaii, New Zealand, Madagascar, or Australia; but your own backyard is not immune from this effect, although in a less dramatic, more gradual manner, perhaps.
Eastern gray squirrels are edging out the native western red squirrels, and exotic Black Chinese squirrels out-compete them both when found in the same territories. Bat populations are shifting, and this affects the insect populations that they eat. It is a huge complex web that few of us see very closely when we swat a mosquito, pick a weed out of the garden, watch the squirrels at the park, or go feed the ducks.
You may be interested in getting involved with something like Frogwatch USA: http://www.nwf.org/frogwatchusa/...
at any rate, it is a program to track toads & frogs, since amphibians are "sentinel species" when it comes to water pollution, habitat degradation, and specie threat/extinction. Read their scientific summery at: http://www.nwf.org/frogwatchusa/finalrpt...
