Extension of Trial Methodology Site approved by Community Ranger
We were delighted to meet onsite with the Community Ranger and review our management of the existing Gahnia Grove site, our ad hoc release of a few of the nearest trees from the Japanese honeysuckle invasion of neighbouring canopy margin to the North, and our proposed extension downhill to the Top Forest path, encompassing an area of almost weed-free (other than radiata and Black pines) Tanekaha and other podocarp/broadleaf regeneration, with extensive moss beds and many species of kauri dry ridge community in a dense understorey.
To provide meaningful data on plant communities and their restoration, it is necessary to differentiate this site, which we are referring to here as Tanekaha Ridge, with its species list, habitats and management, from the Gahnia Grove roadside grass margin site where benign exotic herbs are currently occupying a large area of previous dense exotic vine, shrub and grass invasions.
Some observations of our Tanekaha Ridge surveys to date, and ad hoc weed control during those surveys, have already been uploaded. Tanekaha Ridge will eventually have named subsites to follow particular communities of interest within it, particularly in relation to its margins and neighbouring weed invasions.
A Project for Tanekaha Ridge

is now part of the Gahnia Grove Umbrella Project,
https://inaturalist.nz/projects/gahnia-grove-umbrella-project
while the observations for Gahnia Grove should be unaffected, here at https://inaturalist.nz/projects/gahnia-grove-site-summary-and-discussion
For useful data on the time requirements of manual restoration by this method, expected to continue to diminish at the Gahnia Grove site, we are recording the hours of site work separately. Other time spent, eg liaison, monitoring, data collection and presentation, are combined for both sites. All data will continue to be presented in the Gahnia Grove reports.
