Recently I have read some threads that are incredibly disheartening.
I'd like to share something written by a woman who obviously has an unwavering respect for our lands.
From this website-
"'We should be humble; we may never fully understand the invasion process, particularly for each of the hundreds of potentially invasive species in each of our many ecosystems. One truth is clear: as time passes, many species will spread to new areas or increase in density if controlling actions are delayed.' Putting 'out of place' plants on plant lists is, in most cases, the only way weed scientists have been able to create effective prevention programs because scientific proof is difficult to come by (Parker and Reichard 1998; see Results for the industry's desire for scientific proof)."
