<!-- DIV {margin:0px;}-->I'vebeen thinking about plants labeled as invasive
species and how many ofthem have extremely positive aspects. Much time,
effort, and money isspent fighting these plants, but perhaps our energies could
be directedin more fruitful ways (pun intended).
Coincidentally,a book that I had been reading called "Edible Forest Gardens"
(Jacke& Toensmeier) recomends another book: "Invasion Biology: Critiqueof a
Pseudoscience". I went to the website and found the followingsynopsys of the
book that I thought other's on this list would findinteresting.
Happy composting,

We have all heard the breathless tales of the dangers of "invasive alien
species," butwhat does science say about them? Did you know that studies show
that purple loosestrife doesnot affect species richness of native plants? Or
that it supports higher birddensities than native vegetation? That saltcedar
supports native birds and insects in high numbersand at high levels of
diversity, including endangered species? That the "invasive alien"hydrilla
supports the highest bird species diversity in Florida, and it supports
higherfish species density and many times the fish biomass than natives? That
the zebra mussel increasedthe catch of yellow perch five-fold, and that it
improves water quality? That the so-called"killer algae" reduces pollution and
helps native species? That in all cases,including even oceanic islands,
introduced species have increased biodiversity?
Thoroughly researched, with full citations to scientific literature, this book
will definitelychange your view of introduced species. It will give you the
facts you need to counter thosepromoting invader fears.
Chapters cover the origins of "natural" ecosystems and their changes over time,
and detailthe true underlying causes of "invasion" in the damage industrialism
is wreaking on theplanet. Case studies of many of the most feared "invaders"
are presented, each caseshowing the distortions of the nativists, and the
beneficial effects of the newcomer. The resiliencyof ecosystems and the rapid
ecological integration of newcomers is demonstrated. A chapter detailsthe
growing extremism of the nativist movement, and the harm caused as they
clearcut, bulldoze,herbicide, and burn natural areas around the world in the
name of purifying the landscape of the"foreign," even killing endangered
species as "invaders."
A detailed analysis of the writings of these nativists reveals the
psychopathologies that drive thisreactionary movement. Numerous quotes are
compared which demonstrate that the same fears thatunderlie xenophobia, racism,
and fascism fuel the anti-invader movement. A chapter covers in detailthe
pseudoscientific nature of invasion biology-why the invasive species model
cannot bescientific, and the poor practices that characterize the field. The
impossibility of predictinginvasions is covered, showing the "white list"
concept to be useless as public policy.
The hidden influence of the herbicide industry is exposed. The regulatory
industry and corporateinterests are colluding in an effort to leverage the
fictitious "invasion crisis" into asystem of complete bureaucratic control of
nature, and corporate privatization of the earth'sbiological diversity.
The final chapters concern the beneficial, diversifying effects of
anthropogenic dispersal-themovement of species by man. These species increase
biological diversity, benefit ecosystems, preventextinctions, and act as an
important force for healing the planet. Dispersal is a powerful drivingforce of
evolution, and the book concludes by pointing out a new direction for
conservation-theincorporation of dispersal as an essential strategy.
