Castle Green Forest II

An urban forest to mitigate pollution and bring biodiversity.

Miyawaki Method
Pocket Forest

The forest will act directly on its local environment. This area is heavily polluted and an urban biodiversity desert.  The denseness of the Miyawaki method allows maximum potential Co2 drawdown and pollution mitigation. The trees chosen will also be the ones that have evolved to live and even thrive in the urban environment.

“The Castle Green Forest is an example of bringing an urban forest right into the heart of where they are needed most. This area is heavily polluted and lacking biodiversity. The dense forest will go some way to mitigating airborne pollution and provide a peaceful haven for biodiversity to set up home and thrive amongst the urban sprawl.”

Forest Report: 1 Year

DATE: 28.11.2022

Survival Rate: 92%

Average of Tallest 3 Trees: 160cm

This forest is doing well at 1 year old, having adapted well to the exposed conditions in the park, and is bringing a visible change to this former biodiversity desert. The sounds of bugs and birds can be heard as you stand by the forest, a welcome counterbalance to the busy traffic of the Ripple road nearby.

Soil formation is good with high levels of visible fungi hyphae that will have a highly beneficial effect on the long term health of the trees.

The tallest species currently is the wild cherry (Prunus avium) at 160cm, with a girth of 18mm.

Biodiversity Notes:

Many ladybirds (Coccinellidae) have been seen. Rosehips are also present, blooming on the dog rose (Rosa canina). Rosehips are valuable for supporting wildlife, and will be a welcome source of food for birds this coming autumn and winter.
