Climate Refugees

Did you notice the environmental subtext in the latest Star Wars movie contrasting the despoiled, brown desert world with the overgrown blue-green planet where freedom reigns?  It strains credulity to think that life could be sustained as depicted on the desert planet, while the blue-green planet offers a multitude of niches where creatures could luxuriate.  Earth is a mix of these two worlds, but with the desert gaining more ground every year.

Included in the desert are many cityscapes that are denuded of flora, paved over, serving as commons for swarms of seemingly unconcerned occupants.  This has been our direction since the time of Nimrod and the industrial revolution magnified the devastation many times over.  David Holmgren classes the two types of environment as results of brown- and green-tech.

Maryland is on course for more land "development" in the years ahead, but forest canopy cover is required to be a minimum of 40%, meaning we won't end up like the desert planet.  Other parts of our country will, namely the half west of the Mississippi (excluding the Northwest).  We and our neighboring states are sure to be the recipient of millions of internally displaced people (IDP's) coming from those deserted areas.  We will have to show them how to live a green-tech existence, e.g. forest gardening, if they are not to desertify our end of the continent, as well.

Masses of Arabs huddled around an occasional jihadist are yearning to be free of the civil wars in their desert homelands.  How able, not to mention willing, are we to rescue these refugees when there will soon be millions of our own in similar plights?  How about we settle any of these desert-acclimated migrants in the hot, dry West?  Perhaps they can show some Americans how to deal with the desert and when ours can't stand the heat any longer, maybe we will have learned how to accommodate refugees well enough to settle westerners in the florid east.

Pushing back the Invaders

There is something of a tragedy in places where natives are driven into minority status.  Who knows what the waves of climate and resource war migrations will do to Europe in terms of cultural upheaval? The wild kingdom endures its own invasions of animals, plants, and insects, driven, as well, by climate change and human exploitation.  Often, the invasive species can be predatory, as were the settlers vs. the Native Americans and certain Islamic extremists living in the free world.

As a master gardener intern, I've been trained to side with the natives in their fight to possess territory.  This sounds like a convenient simplifying precept until you start asking for native plants at local nurseries.  Browsing through the Native Plant Guide for the Chesapeake Bay Watershed, I picked four ground cover plants that I decided to shop for to get the best price from nurseries as far as 50 miles away.  It turned out that price wasn't the issue, since not a single one was available at any of the half dozen nurseries shopped.

It seems that the online shopping option will be the solution to this apparent lack of conservation consciousness.  If I don't want to buy in quantities of 25 or greater from the Maryland Online Nursery, I can still buy numerous native species at Izel Plants, the Amazon.com of native plants.  Izel (meaning "unique" in a Native American language), is a clearinghouse for nurseries specializing in native plants.  Prices appear to be relatively low, and include quantity discounts.  The mid-Atlantic region is their strongest sector.

Should neither of these sources carry the plants I want, there are other listings yet to be explored.  As mentioned earlier, the local annual Master Gardener plant sale is a real good shopping opportunity, as well.

Fruits and Nuts

The forest garden I intend to plant will consist of 25 black walnut trees and several compatible species.  That limits the field to only a few species which don't seem to mind the juglone (5-hydroxy-alphanapthaquinone) that black walnut roots secrete.  A recommended native plant guild for black walnut* from Maryland permaculturist Michael Judd consists of:

• Goumi bush - producing a juicy, red berry in June (use 2 varieties; won't tolerate wet soil)
• Persimmon* - delicious Diospyros (Food of the Gods) virginiana (requires full sun; dioecious {requires a male tree}; half the height of black walnut)
• Paw paw - custard cream tropical fruit for making smoothies (full sun best; half the height of persimmon)
• Mulberry - exotic berry flavor (tolerates shade; a bit larger than paw paw tree)
• Currants - tart to sweet from black to pink nutritious berries (a shrub that grows well next to trees)
• Black raspberry - (not out-of-control like blackberries)
• Alpine strawberry - smaller fruit than commercial varieties (ground cover)
• Elderberry* - small, juicy fruit in June/July (likes wet soil, so double up the biochar; to 12')
• Goldenseal - flowery (medicinal) herb

* Available cheap through the Maryland online nursery.  Plant one in every patch.

If there is any room left over in some of these patches, other plants might be considered for inclusion. Everything else should be planted 50 feet or more away from the black walnut to prevent juglone poisoning, which means all these patches have to be well away from my existing plantings.

A Candy Store

Speaking of treasure troves, stumbling across the new Maryland online nursery has opened up a glorious new chapter in my forest gardening efforts.  Whereas, formerly, the only affordable and accessible source for me to buy native plants was the annual Master Gardener plant sale in Prince Frederick, where I would have to pay at least double the online nursery price, plants are now available online throughout the growing season and early orders are possible.  A minimum order of 25 plants is required and a minimum shipping charge of $20 applies to each order ($30 if your state doesn't adjoin Maryland).  Considering that retail nurseries charge over $150 for a young tree, and you could get 150 seedlings at this website for that price, it's a huge bargain.

This outlet is not for commercial resellers.  As the DNR website stipulates:

"Landowners who purchase seedlings from the John S. Ayton Nursery agree to:

• Provide a planting report upon department request
• Protect plantings as much as possible from fires, grazing animals and trespassers
• Keep live, rooted trees in place (trees with roots attached may not be uprooted for sale as live or ornamental trees)"

If you are on the Eastern shore and want to see the farm with over 3 million seedlings, their address is:

John S. Ayton State Tree Nursery
3424 Gallagher Road
Preston, MD 21655,

(a place sure to appeal to at least one of my loyal readers ; )

Rather than rush into ordering, my focus will first be on establishing food forest patches where the seedlings can be planted throughout my property.  This process of sheet mulching requires a year for wood chips and leaves to break down before planting can begin.  My goal is at least 25 patches on my property ready for planting by 2018. 

Please Don't Feed the Algae

Global warming isn't the primary cause of all environmental problems, but it still plays a hand in most.  Take the Upper Middle River outside of Baltimore where, last month, 200,000 fish were suffocated by an algae bloom that led to anaerobic conditions in the water.  The algae bloomed from a combination of warm temperature and an over-abundance of nutrients in the water.  When the weather cooled, the algae died, decaying through a chain of microbial feeding frenzies that consumed dissolved oxygen and released toxins damaging fishes' gills.  Dead fish compounded the effect of dead algae. Not to say that we will suffocate from all of the die-offs occurring around us (though the oxygen concentration in our air is falling), but this is an example of how the fate of a lesser ecosystem occupant can dramatically affect higher species.

The Maryland Department of the Environment has not identified any single pollution source as the trigger for the algae bloom, but leaves open the possibility that an accumulation of nutrients (read "fertilizer") could be to blame. It will be poetic justice when, in the coming decades, the rising seas reclaim the land surrounding this Chesapeake Bay tributary away from homeowners who prized their lawns while poisoning more sentient creatures.

Yet, if cumulative small trespasses can lead to ecological disasters, abundantly small acts of stewardship may also mitigate others.  If you have forested land anywhere in the Chesapeake Bay watershed, Forests for the Bay is a resource treasure trove that can help you care for it.  It takes only a 1 minute free sign up process to open up the treasure house.

Insanity Checks

Now that the COP-21 Paris climate confab has devolved into muddling over short-term economic privilege instead of the physical threat of global warming, let's see how this sharpens our focus of future first-order impacts nearer to home.  Taking at face value the effects listed in the draft 2015 Maryland Greenhouse Gas Reduction Act Plan, we can assume that the worst case is now the most likely within most of our lifetimes, since Maryland's and most other parties' minuscule contributions to the solution will be of little consequence against the outpouring of fossil fuel and peat gas emissions arising from the Far and Middle East.  Here are aspects of Maryland's inescapable future environment and some checks on future decisions that could prove insane if we follow our usual course.

1. Sea Level Rise over 4 feet: The U.S. Navy has new port real estate at the Solomons Recreation Center in lieu of the industrial area.  Midshipmen at the U.S. Naval Academy can make it to their seamanship classes only if they can skillfully navigate a boat through the canals leading to Luce Hall.  All over the shoreline, beaches have become cliffs and cliffs have become beaches. The value of waterfront property declines precipitously.  Implications for infrastructure: question any decisions involving new development near the Bay.
2. North and South Polar Ice Melts: Solomons Island is now an island, indeed.  The Chesapeake Biological Laboratory has a 360-degree view of their subject matter.  Your fortunate friends who once gazed from their patios at the water are now unfortunate (former) friends who now envy your choice of more insular habitat.  The Cove Point Community that once stood up to Dominion Power must now flee King Neptune.  Broomes Island is swept away.  The 231 bridge to Benedict is gone.  The Atlantic Test Range Facilities are put to the ultimate Atlantic test. The U.S. Naval Academy holds all training now in lifeboats.  Both Baltimore and Washington, DC have soggy bottoms, but nothing in comparison to Norfolk, VA.  The U.S. Navy's Atlantic Fleet is nearly defunct. Implications for infrastructure: don't tear down any upland facilities of sound construction, as possible substitutes for those washed out to sea.
3. Heavy Precipitation Events: Occasional flooding of streams and rivers endangers properties situated thereon, devaluing them, as well. Untreated sewage pours into rivers and bays, making parts of the region resemble scenes out of India.  Implications for infrastructure: higher ground is more valuable real estate, but rainwater catchment becomes critical.
4. Heat Waves: Maryland is the lazy South. It's slow down or die from heat stroke. Traditional crops fail from daytime heat and lack of cool nights. Biochar saves the day for those with the foresight to deploy it early. Meat is a luxury as livestock are ever more difficult to sustain. Implications for infrastructure: Make solar power a priority, especially where large air conditioning demand exists.  Value trees that shade your roof. Use biochar in your garden or farm.
5. Ecosystems shifting: Changes in climate are too extreme for many species to adapt, causing imbalances to established equilibria, leading to species extinctions, causing loss of biodiversity, spiraling into devastation of ecosystems.  Ecosystem services are no longer available.  Life suffers. Implications for infrastructure:  forests and forest gardens, linked by corridors, can prop up some of the hardier species to maintain adequate ecosystems that may resurge once the human population is sufficiently extinguished due to its own folly.
6. Increases in pests: Winter, which often eradicates insect and microbe pests, is now mild allowing pestilence to gain strength earlier in the growing season, reducing agricultural yields. Implications for agriculture: Disease resistance and crop diversity is more important in seed selection and propagation.  Mono-cropping big ag has to give way to small-holders who are allowed to save seed.  This is a reversal from current trends in Maryland.
7. Ocean Acidification: Crustaceans cannot grow their shells. Food chains are disrupted. Implications for Maryland: pick a new state symbol.  Crabs will be a relic (except the softshell variety).  Any sea life is probably not a good choice.

You can see it all as just weather, and say that the rain falls on the just and the unjust equally, or you can see it as Noah did and start doing something to try to save your family, or perhaps even your community, state or region.

Keep the Home Fires Burning

Most analyses of the greenhouse gas emissions problem hold the precept that we cannot quickly reduce our use of energy.  Hence, the introduction of technology to displace fossil fuel usage with more sustainable sources must serve as a substitute source of energy.  Oftentimes, the substitute is nearly as polluting as the original, or of dubious marginal value since it is difficult to estimate emissions from all potential sources.

Likewise, it is difficult to estimate the contribution of ecosystems to CO2 reduction.  This is why biochar is struggling to be recognized as an important, if small, part of the solution to the problem of global warming.  Biochar is made with little, if any, production of useful energy compared to incineration of biomass, which produces little, if any, biochar.  This is why the National Academy of Sciences gave biochar such short shrift in their recent study of carbon sequestration approaches. Maryland, unfortunately, adopted this study as the basis for sequestration in their climate action plan.

In order to embrace biochar, you have to allow for the possibility that satisfaction can come through many avenues.  Power may not be any more satisfying than assurance of abundant harvests along with restoration of biodiversity and soil health.  Electricity to power an ever more computerized lifestyle may be less satisfying to millions than lungs working to be filled with fresh air, while growing crops to fuel muscles demanding a more intrinsic energy source.

Energy is more fungible than biochar, but not as much as you might think.  Biochar's uses continue to expand beyond even the 55 identified by Ithaka Institute in 2013.  How can such a useful resource be overlooked, simply because it is not a significant source of energy?

Yet, were the world economy to break down today and trade in fossil fuels slow to a trickle, what would many people resort to?  Ubiquitous small outdoor fires for cooking and cleaning would turn into a climate and ecological disaster.  There are better ways to apply current technology to burning of wood. Coupling these with the production of biochar will help insulate us from climate change, peak oil, and financial folly.
