i-Tree Eco project London

[David Humphries]

Perhaps not as much diversity as there needs to be

 

 

 

.

[Kveldssanger]

From a genetic standpoint, certainly. I would suggest a move away from ornamental species (more typically clonal) and a resultant move towards appropriately* genetically (and thus ecologically) diverse species (both intra- and inter-species).

 

* local / justified provenance

The Royal Parks have recently commissioned Treeconomics to undertake an i-Tree report of the tree stock of Hyde Park in Central London.

 

Some of the headlines;

• There are 104 species (45 genera)
• London plane make up 37% Common Lime 10% Sweet Chestnut 6% Horse chestnut 4% English oak 5% Small leafed Lime 3% Silver birch 2% Ash 2% Hawthorn 2% Norway Maple 2% Others 26%
• 3,174 trees recorded (trees measured over 7cm dbh)
• 34.5% tree cover (that's a lot of shade)
• 12.8 million visitors every year

Kensington Gardens to the left, not included in the report.

• 2.71 tonnes of pollution removed
• 3,872 tonnes of carbon storage
• 88 tonnes of carbon sequestered
• 260 tonnes of oxygen produced 

 

• £172,843,688 Amenity valuation (CAVAT)
• £12,246,490 Replacement cost

 

• 2479 trees are in Excellent condition
• 676 trees in Good condition
• 10 trees in Fair condition
• 6 trees in Poor condition
• 3 trees deemed as Critical condition

 

The main (current) threats from P&D come from Massaria disease of Plane & Oak Processionary Moth.

 

These are just some of the interesting headlines that have come from the report.

The full report will be available to download from Treeconomics website.

Always interested in seeing  ITree results. Will be having words with Mr Rogers about allowing 3 trees to reach critical condition though

 

Currently recruiting volunteers for ITree Bristol. Results of that should be fascinating as there really is a diverse range of species across the City.

I'll try and find out.

 

it won't be cheap but it's about increasing awareness of tree benefits to the public and the bean counters ergo increasing/maintaining budgets, so potentially a very worthwhile exercise.
