The Great Audit - or the arboreal equivalent of the dooms day book

The Great Audit 

It's been another hot long summer here in Candeleda, nothing new there, but today the clouds partially cover the sun and that makes working in the garden somewhat more tolerable, tearing myself away from my newly discovered Chrome apps, learning to type is one of them ;-) I decided to count how many trees we had, assuming they all survive the summer.

To start with let me point out that I counted the trees on the basis of
  1. I only counted mature trees, mostly anything over 1. 5 meters in height
  2. to count as a single tree they needed to be clearly individual trees and not just a tree with multiple trunks etc
  3. my numbers are precise but not exact
So  the numbers are

Pyrenean Oak (Quercus pyrenaica) -  249

Common Hawthorn (Crataegus monogyna)  48
European Hackberry (Celtis australis) 31
Ash (Fraxinus excelsior) -  14



The Majority are in the top half, which makes senses.

Some interesting observations, at least to me.
The Oak is by far the most common tree but it is also the one whose long term survival is most in doubt due to the disease they are exposed to, another has dries up this year

While there are more Hackberries than Ash trees, they are nowhere near as big so they are Ash trees and so the impression on has is that there are few of them

While the second most common tree is the Hawthorn, few are more than just shrubs, still I include them here as there are two or three examples well over  meters in height

I'll up date this from time to time, just to see how things develop, but I expect to see the oak tree numbers decline over the next few years, hopefully I'll have found a sustainable way of planting new trees
