Apples, crabapples, everywhere…

A large majority of the pink flowered trees you see in and around Boulder County over the past couple of weeks are apple and crabapple trees, and a large portion of the white flowered trees are as well (some are pear or other type of fruit trees, and some are non-fruit bearing trees). All of the crabapples species are in the Malus genus of the Rosaceae famliy.

The apples you see at farmer’s markets, road side stands, grocery stores and everywhere else are all, with exceedingly rare exceptions, descendants of a single species of crabapple, Malus sieversii. M. sieversii is also known as Asian wild crabapple or Almaty crabapple. Almaty is the largest city of the country of Kazakhstan, in central Asia near China. The mountains and hills near Almaty have forests of wild apple trees, just as the mountains and hills of Boulder County have forests of Ponderosa, Spruce and Lodgepole pines.  Imagine our hills and mountains to the west covered with apple trees….

Those wild apple tree forests are being cut down at a rapid pace to clear the land for farms, buildings, roads, and other human infrastructure.  The planet is in the process of losing it’s apple genetic diversity, which is a threat to cultivated apples everywhere.  But, there is something you can do.  The USDA has a collection of wild central Asian M. sieversii at their research station near Lake Geneva, NY.  Scientists with the USDA have conducted genetic studies of these trees, and have determined that a ‘core collection’ of about 100 trees covers about 95% of the genetic diversity represented in the entire collection.  Widespread Malus has been requesting, from the USDA, seeds and scion material from these core collection trees for three years, and working with others around the country (and globe) to share and distribute this core collection of apple genetic wealth.  If you would like to participate, please get in touch with us, see our contact page, and let us know.  You do not need to know anything about apples trees, or need much space to grow a tree.  We can help you with choosing an appropriate tree for your space and level of interest.  We only ask that we have access to the tree in the future to gather scion material and some of the fruit (and the seeds)  if we need it.  We are out of trees to plant for 2016, but please sign up for planting in the spring of 2017.  Letting us know now helps us prepare trees for next year.

Who’s doing what with apple biodiversity?

I thought it would be nice to have a list of projects working to protect apple biodiversity in North America (or elsewhere, if any readers can add information in the comments). Here’s a start:

  • Widespread Malus … that’s us! Working to build a highly diverse collection of Malus sieversii, as well as distribute scions, grafted trees, and seedlings.
  • Apple Diversity Group … a collaboration between Dalhousie University and Agriculture Canada, this group’s Apple Biodiversity Collection in Nova Scotia has 1000+ different apples, including about a hundred Malus sieversii.
  • USDA Plant Genetic Resources Unit … located in Geneva, NY, USDA PGRU maintains one of the world’s most extensive apple collections, including diverse wild apples (M. sieversii, M. orientalis, and others). Interested members of the public may request open-pollinated M. sieversii seed from PGRU.
  • Temperate Orchard Conservancy … located in Oregon, TOC is replicating the Botner Collection (perhaps the largest private collection of apples in the world … 4,500 different apples).
  • Montezuma Orchard Restoration Project … promoting apples and orchards in Montezuma County, Colorado and around the state. Also locating and propagating rare Colorado Heritage apples.
  • North American Fruit Explorers … a group of folks interested in all kinds of fruit. There are quite a few members with their own diverse collections of apples and other fruit. Visit the web site or the facebook page.
  • Seed Savers Exchange … not just for seeds! Iowa-based SSE has quite a nice collection of apples (hundreds), and numerous members who share apple scions with other members.
  • Agrarian Sharing Network … is sharing diverse fruit and vegetable material in the Pacific Northwest. ASN has done extensive evaluations and cloning of the Botner collection and several other large bioregional collections, and is involved in a number of propagation fairs.

Can you help us add more projects to this list? Please send us an email!

312 apples grafted, and counting!

We’ve got 200+ trees grafted for 63rd Street Farm, to be planted out later this month. Also, a few for giveaways, and maybe 50 Malus sieversii grafted from scions received from USDA in Geneva, NY. There are about 15 Antonovka rootstocks left to graft … most of these will be grafted with Malus sieversii.
