Blackley Forest is a site of biological importance and a fine example of one of the country's first Community Woodlands. Planted to commemorate fallen soldiers of the Second World War, the Forest is a diverse mix of woodland, grassland and wetlands, dissected by a well established network of paths and steps. The River Irk can be seen in its most natural state, fringed by birch trees with some colonies of autumn crocus.

Although the majority of woodland was planted in 1953, there are areas of alder coppice that may date back much farther. Beech dominates the southern edge of the site, with birch, oak and ash woodland developing at the northern tip. There are some interesting heather and cotton grass communities growing on the site, and the Forest plays host to many species of flora and fauna.

Currently, work is being undertaken to reinstate the river bank, following years or erosion. This work is being carried out with environmental and aesthetic issues in mind, and will upon completion be landscaped in a way which reflects the woodland surrounds.

Early in 2006 a site was located for a dipping platform close to the Victoria
Avenue entrance; this development would enable full disabled access and serve as an educational facility.

The footpath installation around the top pond, funded by the King William fishing club, was completed by the end of January 06

With the assistance of MCC Environmental Campaigns, a highly successful school visit by Holy Trinity took place. Pupils took part in tree dressing, a guided walk involving tree identification, leaf identification and bark rubbings.

Over the past 2 years, the Irk Valley Project has worked to reintroduce appropriate ground flora to Blackley Forest. It started with planting small areas of wildflowers within the forest which are monitored by the Friends of Blackley Forest. The aim of the project is to determine which plants are appropriate for the forest and plant in larger numbers in the future.

From January 2007, a BBC Breathing Places Lottery grant is being used to make improvements in the forest, for example the steps at Kendall Road have been refurbished.

The friends have undertaken a number of successful health walks and a Bat walk held in summer 2007 was attended by 43 people.
