I mentioned on Twitter that more trees had failed to leaf out this spring, victims of the long drought which not only did not provide them enough water to survive, but prevented us from having any supplemental water to give them.   Someone suggested what seemed reasonable–why not plant trees from the next climate zone (or two) to the south of us.    I realized then that the traditional “planting zone/climate zone” concept had taken hold to such an extent that the complexity of keeping anything alive through a rapid change of climate wasn’t being talked about.

This is another year of brown spring and summer…though some people got more rain, we’re still behind, and the quick brown-off after the rain we did get proves it.

This is not how the land should look in early June: we should still have at least half the grass green, and the June flowers in full bloom.    This is a typical August picture: brown land, hard blue cloudless sky full of heat.   Before climate change really began to show here,  mid-June to mid-July looked more like the picture at the top of the blog.   But this is the third dry year, though we had enough rain in April and early May to produce thi river of gold (claspleaf coneflower) in mid-May, in the lowest part, where water had run for a few days.

Carbon sequestration is the trapping of atmospheric carbon (carbon dioxide) into some form where it can stay for decades.    Carbon sequestration occurs naturally by the actions of plants, especially long-lived vegetation, and in certain soils, where it’s deposited as slow-decaying organic matter.   Plants use sunlight to convert atmospheric carbon dioxide into the chemical that make up plant material–simple sugars, to start with, then starches and more complex chemicals when added to other nutrients.

Why is this of interest in wildlife management or prairie restoration?    The obvious reason is climate change caused by increasing carbon dioxide levels.    Carbon sequestration by changes in management of both public and private lands is one way to get carbon dioxide out of the atmosphere  and into plant materials.    Many of the things a land manager might do to promote wildlife or restore an original ecosystem (forest or grassland)  will have multiple benefits…including carbon sequestration.

Taking the train from Texas to the NE has let me watch autumn develop: just starting in Texas, more and more advanced as we went north, and here, in upstate NY, gorgeous with sugar maples, sumac, poison ivy (leaves the size of dessert plates), things with berries I don’t know, green moss and ferns, russet this and golden that.

I chatted with another prairie person in St. Louis at the Ninc conference and in Oswego visited Rice Creek Field Station and met the new director, whose previous work was in  Chihuahuan Desert ecology–and then walked the trails there.  Perfect.  She’s aware of research in Mexico on the effect of climate change and has promised to send me some references.

Meanwhile, I’m hearing reports from home of more rain and thus the creek may well still be running when I’m home again, a week from this Sunday.

Since habitat management is part of wildlife management, restoration of degraded or poor habitat is part of our job as wildlife managers.   The basic concepts were laid down years ago…but the devil’s in the details, as usual.   The July 31, 2009 Science had an entire section on restoration ecology, with examples drawn from around the world showing the benefits, costs, and difficulties in this field.  Especially with the advent of global warming.
