To prune or not to prune in a dense stand of Haloragis erecta (Shrubby toatoa) with a few light-loving seedlings beneath

Recently enjoyed some discussion with a fellow iNaturalist.nz restorationist about Haloragis erecta as a nurse plant for native seedlings, and whether the dense stand of toatoa that arose near the top of CHF Bank in gahnia Grove might have supported more development of the ti kouka and karamu seedlings beneath it if it had been pruned at some stage.

Having thought it all over both onsite and off, our conclusion is that light-loving seedlings under the shade of the interior of a dense toatoa stand would benefit from a bit of release, ie pruning the toatoa above them.

However, since such a large area had been cleared of shrub and vine weeds that you can't really go halfway with, the main objective last summer was to get ANYTHING not too aggressive covering the ground. The Verbena, carrot and oxtongue, with nightshades, did a splendid job, and the toatoa were a plus, along with the Solanum opacum, in that they were native so "permanent" cover.

Since the drought last year was from about February to June and the ground was only really wet for a few weeks, I would do the same again- ie make moisture retention the priority, for the existing few trees and the most benign of the exotics.

The seedlings that have developed to about 30cm are all either under trees or within 1m of the canopy margin at the bottom of the bank. The seedlings that developed under toatoa were also in partial shade from a recovering karamu gradually leafing up after release from honeysuckle, and they were on the outer edge of the dense toatoa stand, which is still sheltering them nicely, the exotics having been successively removed as the karamu leafed out.
