To coincide with the start of spring and increased amount of wildlife activity on the site, this week will see a big increase in the amount of ecology work being carried out on the Olympic Park.
Despite the previous industrial use and years of neglect, the area - particularly the wetlands, waterways and woodlands - contains natural habitats for several species of fish, bird, bat and newt.
It is therefore important that we start to identify and relocate any species that live in habitats that could be affected by an increased amount of work near them.
We have started newt surveys in Bully Point Pond in the north of the site, and last night over 150 smooth newts and many toad tadpoles were collected.
These will all be now safety relocated to their new home in the Waterworks Nature Reserve, just down the road in Leyton.
Today it was the turn of the fish in the Pudding Mill River to be found a better home. The stretch of water is stagnant and although not a healthy spawning ground, it could contain fish such as eels, tench, bream and pike.
Aquatic experts spent yesterday preparing the stretch of water by clearing the pennywort that covered the surface to help ensure that any fish could be found and retrieved.
Today they set out in a dinghy and began a process of inserting a mild current into the water to attract any fish and momentarily stun them so they could be scooped out of the river.
Only a few eels and a handful of pike were found in the end but they have now been relocated to the better water of the River Lea a few hundred metres away.
Other projects will include more newt and other amphibian relocations and also the creation of kingfisher and sandmartin artificial nests. And I will be heading out on some dusk trips to check for black redstart birds and bat activity.
