In a recent NY Times article, Zoë Schlanger describes a policy shift in managing our national parks, from protecting all species within our parks to picking a choosing which ones we have the resources to save. Climate change is blamed as the culprit that has pushed park managers and budgets beyond their capacity, although most of the actual problems described in the article are caused by invasive species we have brought to this country and would be problematic even without climate change. Climate change is indeed serious management issue, though not the only issue, and it has shown us the limitations of restricting conservation to parks and preserves. Parks are fixed in location, but a changing climate demands flexible responses on the part of plants and animals they are designed to protect. When confined to a fixed space, they lose that flexibility.

I have been asked several times in the last two weeks just when it’s safe to get rid of leaf litter without hurting the insects that have spent the winter within it. An urban legend called the 50 degree rule seems to be very popular these days, but it is just that: an urban legend. I am hearing that all insects will have emerged from your leaf litter or the dead stalks of your meadow plants after varying numbers of days when the daytime temperature is above 50 degrees: 5 consecutive days over 50 degrees, 7-10 days consecutive days above 50, or just several days above 50 whether or not they are consecutive are all popular counts.

I thought I would open this, our first newsletter, with a reiteration of what Homegrown National Park™ is all about, and why it and other conservation efforts around the world are so urgently needed today. There have been 5 great extinction events in the history of life on earth; each one came close to eliminating life altogether and after each one, it took many millions of years for life to rebound in the form of new species.
