Kellaway Cres Plant Protection Zone

Description

A site of recent road works which has arisen an impressive plethora of plant life. Well over 130 species have emerged; a number of which are rare and highly unusual locally. And it's far from finished revealing its surprises.

The major disturbance of the soil brought on by machinery has caused long dormant seeds to 're-awaken' with the right conditions coming to light. The last time the soil was disturbed here was during WWII when the site was used for allotments. Know your place 1946 aerial shows how the place would have looked. Some of the plants recorded are clear garden escapes or birdseed aliens; having been deposited more recently but the majority are often associated as being colonising species - which lack the ability to compete and so require regular disturbance to remain permanent such as in cultivated land. Otherwise their presence disappears in all but the form of set seeds - organic 'time capsules' which wait and can remain viable in the soil's 'seed bank' for a very long time - often tens, hundreds and sometimes even thousands of years!

Many surprising species have 'popped up' here but by far the most incredible find has been Cat-mint (Nepeta cataria) - a plant which was previously considered extinct in Bristol! It was last recorded from Kingsweston Down in 1907 after an absence of well over 100 years! It has come back from the dead!

Future Management:

The spot will remain uncut over the winter and for the whole of next summer to allow the Cat-mint and other biennial and perennial species to set seed (some of which will be collected as backup). After this period the site will be razed to the ground and turned over with a special rotavator machine ('the Blackenator!') which heavily disturbs the surface, bringing it back to square one and the site left alone again for the cycle to continue. This process will be repeated every 2 or 3 years ensuring a near permanent presence for all the plants existing here.
