The Yale, the usda and the nsf sites have a number of good articles giving
stats like you are searching for, you have to search around for them.

Regarding: 

"Native plants provide food and shelter for birds, butterflies and other
desirable wildlife. Many help to enrich the soil. Their root systems help
rainfall percolate into the soil, reducing erosion and runoff. This
improves water quality." on the Wild Ones web site and similar statements
on other web sites, I am looking for actual statistical studies that give
percent increase in nutrients such as Nitrogen and Phosphorus, sediment, or
storm water run-off in mono-cultural patches or plots of non-native
invasive plants in natural areas compared to native plant plots in a
bio-diverse ecosystem. This will help folks get funding under the new 
grants to protect the Chesapeake Bay and other watersheds. We have such
information for Microstegium but need it for other species. Best regards.
