What to do with fallen trees

Westchester County was severely battered by Hurricane Sandy last week, which caused  massive flooding along the coast, extensive power outages, property damage and the death of thousands of trees.  In Pound Ridge, first comes the storm, then comes the chainsaws.  For the past week, the soundtrack to my life has been the buzz of a small motor pushing saw teeth through living wood.  Armies of landscapers, town workers and contractors have been busy cutting up all the trees that lay across peoples driveways, the public roads and hang from power lines.  I myself have been clearing the trails on the Pound Ridge Land Conservancy’s preserves.

What happens to all of these fallen trees?  Where does the wood go?  From my observations, if a tree falls on someone’s property it gets cut up and is either 1) removed from the property or 2) stacked (perhaps for firewood?).  While it is great to use your downed trees as firewood and/or any other domestic use, I want to give some attention the practice of simply letting your property keep the wood.  
A downed tree is very useful to your backyard ecosystem.

Rooting for the underdog: eastern bluebirds

Imagine you live inside of a tree.  Your hunger forces you down to the ground where you glean ants and worms out of the grass.  Upon returning to your tree you find a strange bird comfortably occupying your home.  Its time to move.

This has happened again and again to the eastern bluebird, which live in small holes in trees.  The non native European starling and house sparrow (both intoduced to the Americas after the Columbian exchange) pose a serious threat to the bluebirds: starlings (another ‘cavity-nesting’ bird) enter bluebird cavities and evict the occupants while house sparrows kill bluebirds and/or destroy bluebird eggs.  Its a rough world for the adorable bluebird, which are also negatively affected by severe winters and loss of habitat. 

The bluebird has been subject to an extremely dynamic and turbulent history in North America. See here for a nice synthesis of their history.  To sum it up, due to loss of habitat, land conversion, and the introduction of non native birds (European starling and house sparrow), the bluebird population crashed around the middle of the 20th century.  Their numbers were so low that by the 1960’s birders and scientists feared that bluebirds may actually become extinct.  A widespread, grass-roots movement to save the bluebird ignited a new interest in their plight, research for their conservation and the spread of bluebird boxes across the country.       

Bluebird boxes?  Yes, there is something that you can do to help the bluebird! 

To mimic the tree cavities that bluebirds find so comfortable, scientists, conservationists, nature enthusiasts, birders and school children have built and errected small wooden homes for the bluebirds, A.K.A., bluebird boxes.  These easy to build boxes provide bluebirds with a safe place to make a nest and bring up their babies. European starlings are too big to fit through the door hole which means that the bluebird family is safe from unwanted squatters and killers.

This type of human mitigation has truly paid off; bluebird populations have responded to the wide-spread use of bluebird boxes.  Their numbers are up, but still not as high as they were before humans severely impacted them with starlings, sparrows and sprawl.  Choosing to erect a bluebird house is still a fun and worthwhile endevour – one that directly helps wild animals survive in the face of serious human-induced obstacles.  You can see working bluebird boxes in the meadows at the Pound Ridge Land Conservancy’s Clark Preserve and the Westchester County’s Ward-Pound Ridge Reservation

If you want to build or buy a bluebird box you should consult the many websites dedicated to bluebirds to understand their specific habitat and ecological requirements.  Here are a few websites:

Out with the lawn, in with the meadow

In last week’s blog post I reported that the Pound Ridge Land Conservancy recently oversaw the mowing of their five-acre meadow on the Clark Preserve as a way of preserving it as an open habitat and supporting the animals that call it home.  This week, the meadow conversation continues with a focus on all the cool ways that people are bringing meadows and meadow plants into their landscaping.  Really big meadows like the ones at Ward-Pound Ridge Reservation are impressive, but not feasible for the average landowner to own or maintain.  The alternative?  Small meadow gardens.        

Out with the lawn, in with the meadow!
Native meadows have become a fashionable, beautiful and ecologically intelligent type of landscaping over the past decade. Their benefits abound: they require far less water and mowing than a manicured lawn, they require ZERO fertilizers, their appearance changes with the seasons, they support populations of native plants and they attract a variety of wildlife. My friends in Pound Ridge – James and Ellen Best – have beautiful meadows incorporated into their landscaping; their backyard feels less like a generic landscape and more like real nature.  Here is what James and Ellen Best have to say about their meadow gardens:

What we like best about meadows is that they dramatically change with the seasons, unlike grass, which hardly changes at all. Cycles of purple, pink and yellow flowers, wispy grasses, buzzing bees and incredible spider webs appear in the meadows; it’s an ongoing show that nature puts on for free. We see fox, hawks, woodchucks, rabbits and more in the natural, protective habitat that the meadows create. After a dry, brownish winter, when the meadow begins to come alive again in the spring, it’s so exciting! Yes, patches of grass offer good foot-feel and space for activities, like a carpet. But how much carpet do you need? Less work, too!

The Bests go on to say:
The combination of having both meadow and lawn areas seems like the best option. We have winding paths running through the meadows, making it an adventure to walk from one area to another. And it doesn’t have to be in a big area to give us that experience. Meadows provide borders and edges, as well as natural transitions from wooded areas to lawn areas – so much more alive than just a mowed lawn!

It seems as if meadow landscapes and native landscapes are popping up all over the place. In just a 20 minute internet search, I found all of the following websites.

Meadow management at the Armstrong Preserve.
On the Pound Ridge Land Conservancy’s Armstrong Preserve there is an old field, which is colonized by invasive stilt grass and japanese barberry.  I recently drafted a Meadow Management Plan for the Pound Ridge Land Conservancy which outlines a long-term plan to bring native meadow plants back to the field.  Over the next five years we can expect more native grasses and wildflowers, bees, butterflies and dragonflies!

A meadow is a terrible thing to waste

The Pound Ridge Land Conservancy owns or holds conservation easements on 17 preserves in Pound Ridge, NY. The biggest – at 70 acres – is the Clark Preserve, on Autumn Ridge Road. This preserve is a fair representation of Pound Ridge’s ecology; up high its got patches of exposed bedrock where oaks hang on for dear life, down low its got wetlands full of red maple and ferns, and everywhere in between grows a dry forest over hilly, rocky terrain. A unique feature of the Clark Preserve, and one that draws many each week, is its beautiful meadow. In the simplist terms, the Clark meadow is a refreshing change of pace; it permits a grand, open view and induces a feeling of expansiveness that the forest can not. Likewise, in ecological terms, the meadow refreshes the landscape; the open, grassy habitat supports mammals, birds, insects and reptiles that the forest does not. The bounty of the meadow interacts with the bounty of the forest to support those animals – such as the fox, hawk or box turtle – that rely on both ecosystems. An ecologist would say that ‘the meadow increases landscape diversity’.   

Here, in the eastern part of the U.S., meadows don’t usually stay meadows for long. This is really a tree’s world and before long, every meadow will become colonized by woody plants. While on one hand this change is totally natural, on the other hand we have a limited amount of meadows left and, without active management, they would simply go away. Essentially, if we want meadows (which a lot of people like for a lot of different reasons) then we must mow them to keep out trees and shrubs. This is exactly what we did at the Clark Preserve last week.

In this picture, half of the Clark meadow is mowed.  By the end of the day, the entire meadow was mowed. 

By mowing the meadow we killed the small shrubs that were starting to grow in the meadow.  The meadow’s non-woody plants – grasses, flowers, ferns, etc. – will grow again next year.  In meadow management, different mowing cycles are used to benefit and attract different animals.  See this pamphlet, put out by the Mianus River Gorge, on the frequency and timing of meadow mowing. 

If meadows naturally turn into woodlands and forests, why should we keep a meadow open? 
Or, asked a slightly different way…
Aren’t we interferring with natural succession when we mow a meadow?
Eastern meadows – when left a lone – usually become colonized by woody shrubs and trees through a somewhat predictable series of vegetation changes.  The following graphic depicts how a place’s plants may change through time. 

A very general depiction of ‘succession’, the change in vegetation over time. 

So yes, it is well known that meadows turn into forests, but this does not mean that meadows are somehow less ‘natural’ or less important than forests.  As landscape features, meadows have always been right alongside forests.  If we consider the entire eastern forest – from the Mississippi River to the Atlantic Ocean – before it was dominated by industrialism, there were thousands of meadows dotting the forested landscape.  Fires would burn and open up forests to create meadows.  Beaver dams, after being breached, would drain their ponds and leave a wide open meadow.  Disturbances such as these were always making meadows out of shrublands and woodlands.  So at the same time as natural succession was turning meadows into forests, the forests themselves were being converted into meadows.  Within this simple equation, there was always a place for meadows in the eastern landscape and, thus, many animals evoloved to live within their open, grassy vistas. 

Today, its a different ballgame: fires are squelched and beavers are a mere fraction of their former abundance.  No meadows are being created while the remaining meadows proceed through succession into forests.  Given enough time, we will simply run out of meadows – hence the need for meadow management.  When we manage for a perpetual meadow we secure habitat for all the butterflies, birds, dragonflies and turtles that rely on them. 

Becuase of their ecological and cultural history, meadows are the focus of conservation in Westchester County.  Many uncommon birds and insects flock to these areas, attracting naturalists with binoculars and cameras.  The following are managed meadows open to the public:

Keeping your garden warm through the fall

Here comes fall again…its seems like just yesterday I had ample daylight to do with as I pleased: after-dinner hikes, early morning bird walks, flexibility to do my garden chores whenever they fit in.  Now, I am scrambling to get everything done before it gets dark.  The revolving seasons change the way we are currently gardening at the Armstrong Education Center.  We can’t create more hours of sunlight, but we can surely govern the micro climate in our garden to keep temperatures  – and production – from dropping too low.  There are many techniques for what is commonly called ‘season extension’, which generally means growing crops beyond their normal outdoor growing season.  Some forms of season extension – such as the greenhouse – certainly ring a bell with most people.  Lesser known methods with interesting names such as ‘row covers‘, ‘hoop houses‘ and ‘cold frames‘ are actually used regularly among small to medium sized agricultural operations.

Row covers, used to extend the growing season, at the Armstrong Education Center.
Underneath the row cover.  Inside, our swiss chard, kale and carrots will get some early winter protection.  

This week at the Armstrong Education Center gardens, Sarah Bush and I installed Agribon AG-19 row covers over our remaining crops of salad greens, carrots, beets and herbs.  This material will provide protection against early frosts and, until then, keep the beds from cooling off on cold nights.  In addition to season extension, row covers are used for a variety of other reasons including pest control and preventing wind damage.  Just googling ‘row covers’ will yield dozens of helpful sites and hundreds of pictures.  
         
On a personal level, learning about row covers and season extension opened my eyes to the commitment, skills, knowledge, and ingenuity of the farming community.  When I first saw season extension I thought “Wow, these people just wont give up!”.  I first encountered season extension in Alaska where, with only a three month growing season I expected not to find many farmers, but I did.  Growers in Alaska take advantage of the looooong days, which help crops grow almost before their eyes.  To get a jumpstart on the late season and to hang onto it as long as possible, the Alaskan growers that I met used various methods of season extension.

Alaska Grown is a state program that promotes Alaska state agriculture

To me, these techniques represent a certain strain of resilience, stubbornness and dedication that I am finding to be universal among food growers.  I am learning from these growers that to keep a productive and sustainable garden requires us to master the art and science raising plants.  At the Armstrong House, productivity and sustainability are goals and in only our first growing year, we are learning a lot.  To increase productivity and sustainability in the future, we have much more planning and learning to do; our row covers are just the beginning.  Stay tuned to see what else we try.

For the region’s authority on growing, gardening, farming and agriculture see Stone Barns.  Visit their website at least, but do yourself a favor and visit their farms, sit in on a class and participate in a workshop.  A recent trip to their greenhouse, hoop houses, orchards and compost arena left me speechless.  They really know how to grow food over there.            

Seasons of want and plenty

I’m not a foodie but I have a couple foodie friends who would rather eat dirt than a winter tomato from the supermarket.  After hearing their arguments and giving my taste buds some time to reflect, I am beginning to agree.  At the Armsrong Education Center, I am trying something new this year: my partner, Sarah, and I bought 40 pounds of organic heirloom tomatos from Amawalk Farm in Katonah, NY, and processed them into sauce for the winter.  Come January, when the mealy tomatoes get shipped in from who knows where, we will be thawing out bags of tomato sauce for pastas, pizzas, chillis and more.  Here is what the process looked like:    
We met a farmer and asked if we could buy slightly damaged tomatoes at a reduced price.  They were happy to sell off tomatoes that weren’t otherwise marketable.  After a quick trip to their farm, we came home with two big boxes of assorted heirloom tomatoes. 

A quick rinse

Some of the tomatoes were a bit under ripe so we set them aside to eat in a few days.  They will not be made into sauce.  This informative pictures appeared on the side of the tomato box.  The tomato faces are cute. 
We cut up the sauce tomatoes and removed any damaged parts.  On average, each tomato had one or two small spots that needed to be cut out and composted.  This step took roughly 2 hours. 
  
We placed the tomatoes into a oven pan and added good olive oil, salt and cloves of garlic.  We broiled the tomatoes for roughly 25 minutes.  We stirred the tray two times to make sure the garlic didn’t burn. 
  

Amazing



We spooned the sauce into freezer bags

Mmmmmmmmmmmmm



What does freezing bags of tomato sauce have to do with Living Lighter on the Land?
1)  Food is nature, nature is food.  We can’t fully understand and appreciate nature without understanding our food and bigger ‘food systems’.  We may not think of a single asparagus plant as part of the ecosystem, but when you consider our country’s land cover, agriculture plays no small role.  In America, the millions of acres of agriculutral land (formerly wild forests, prairies and wetlands) still connect with the greater ecosystems through their soil, water, plants, animals and the atmoshphere.  There’s no two ways about it: our agricultural operations are big part of our new ecosystems.  To rethink your place in nature is to rethink your place in your food system. 
When I thaw out my sauce in the winter I will know exactly where it came from, who picked it, who shipped it, who cleaned it, who cooked it, and who bagged it.  That’s food safety.  Also, I will know how the farm operates, the philosophy of the farmers, how the farmers treat their land and how the farm fits into the greater ecosystem.  That’s land stewardship. 
2) Eating in season, or perhaps more accurately stated, buying in season.  When we buy food out of season, that food gets shipped from very far away.  Southern California and Florida are the closest large winter-food producing regions, and much of our winter food comes from Central and South America.  A tomato that travels 3,000 miles (and the fuel that was required to do so) doesn’t make a lot of sense to me.  I’d rather buy it from a farm five miles away and freeze it.       
Freezing is just one option.  You can pickle, jar, smoke, cure, and dehydrate your food to keep it for the winter.  It’s surely not easier than driving to the supermarket, but it puts you back in control of your food.  Plus, you can feel good knowing that you would have made your grandmother proud. 

Land stewardship is kind of like a cocktail

The more adorable side of conservation

Remember the three R’s: reduce, reuse and recycle?  Well, I just realized that they are listed in order of importance. While recycling is awesome, we should really focus on reducing our consumption and, in the example below, reusing the things we already have.  

This little piece of wall art hangs next to my sink at the Armstrong House Education Center to instruct my guests of our sponge reuse policy. I cannot take credit for this – it was inspired by a friend of mine. Feel free to replicate.  Stay tuned for more adorable conservation-based wall art in the future.  Send me yours and I will post it on the Blog.
