Everything is interconnected in ways that are unimaginably complex. I see this in my reading and in my observations of nature. Because of this I am starting to think that plant sameness both contributes to and is contributed to by animal sameness, especially birds.
Lots of invasive plant species in my area are spread by birds. But which kinds of birds? I'm not sure if we know.
But the species of birds which feed upon the berries of the invasive species, are likely to be highly abundant in the areas overtaken by the invasive species, spreading a larger number of seeds of invasive species into the other areas those birds go. When the high density of invasive plants excludes other birds, it causes even greater density and exclusionary capacity of the invasive species, and even more favorable conditions to the birds that feed upon them.
So basically, when plant sameness reduces the number of animal species (and fungus species) that can survive, and when this plant sameness is repeatedly reinforced through management of the landscape, it can start to perpetuate itself through the animal sameness that was created
What this suggests to me, is that there may be a critical threshold of fragmentation and destruction of habitat where invasive species removal by itself is pointless or worse, because the larger-scale landscape has too much plant sameness and animal sameness for native species to come back.
What to do...? Maybe choose plantings for the restored area specifically for vigorous dispersal and high seed and fruit production?
Native, quasi-native and cultivated food plants could all be appropriate, because the goal is to attract the dispersers that cannot survive in the invasive species monoculture environment and redirect dispersers that previously relied on invasive species for food.
This facilitates dispersal of plants between the newly planted restoration and other habitat fragments that can support non-monocultured wildlife.
Don't think I've seen them all together in one big video like this before
