Bencubbin Year 1 Monitoring

Previous Next

In July of 2018, Carbon Neutral Charitable Fund began to restore 25 hectares of previously cleared land to native Acacia and Sandalwood woodland in Bencubbin, Western Australia.

In July 2019 we conducted year 1 monitoring on the site to determine how the seedlings are surviving so far.

10 quadrats of 19.5m by 19.5m randomly scattered around the planting were surveyed, counting the number of present seedlings and measuring the height, width and percentage of alive biomass on each plant. We found that on average, across the planting, we had 98% survival.

Delving deeper into the results it can be seen that the results were very mixed across the planting, some areas showing 0% survival and others showing over 300% survival. We suggest this may have been due to an uneven distribution of seeds and seedlings when establishing the planting.

Other issues that we observed while monitoring was the presence of weeds such as paddy melons and some damage to plants that could have been cause by rabbits. Carbon Neutral Charitable Fund endeavours to minimise threats to establishing plants and so will look into management methods of these issues to improve the planting’s survival chances.

Despite this, we are so happy that the numbers are still high and the plants are all healthy, having survived all four seasons. We will now look to infill the site to encourage an even greater restoration of native vegetation in Bencubbin.
