Fifteen years of restoration

To celebrate fifteen years of restoration by volunteers in Mangaiti Gully we produced a photo book for all our past and present volunteers. It is hard to imagine what our section of the gully looked like back in 2010. There were no tracks, with honeysuckle, blackberry and grey willow dominating the wet gully floor. Clearing and planting was done section by section. First build a track to gain access, then drill and poison the willows followed by clearing the honeysuckle and blackberry predominately by hand. There was minimal spray used back then. As the tracks were built, they were gradually connected. The public then started to use them at which stage they were upgraded to what they are today. A highly successful public asset for our city.

Juvenile weta

We have been collecting bamboo stakes from the field that are no longer necessary to hold up previous plantings. These will be repainted with coloured tips and reused next planting season. They were being stored in a garage. In the evening when the garage was being inspected to secure it for the night little weta were noticed emerging from some of the bamboo stakes. Seven in total were collected and returned to the gully to carry on their lives. The photo of a weta sitting on a finger shows how small these juvenile weta are. It is interesting to see how long the antennas are. They are out of all proportion to the size of their small bodies.

A snail collection!

See photo. This was taken when servicing one of our rat bait lines. A thrush (or maybe a blackbird) is using the block of wood as a convenient bashing post to break the snail shells to get to the succulent snail inside.

Annual spring tracking tunnel monitoring

We monitor rats across the full 30 hectares of Mangaiti Gully in the spring and autumn to see if our control programme is doing what it is supposed to. Rats are known to be smart. This can lead to rats learning how a programme works and, over time, start to avoid some traps or toxins leading to an increase in the rat population. This is why regular monitoring is important. Thankfully there is no sign of this happening at present. There was only one rat recorded down by Wairere Dive, Hukanui Road end this spring.

Wineberries are a great pioneer species

Wineberry (Aristotelia serrata) is showing clusters of pink flowers in the gully this spring. Wineberry is a good food source for our birds offering them nectar, fruit and seeds. It is a great tree to plant at the very early (pioneer) stage of any restoration planting. They grow large enough to shade out pesky weeds. They seed at an early stage in their life. With the help of bird dispersal, it creates natural seedlings throughout a restoration area.
