The planting activity this month saw a good turnout of members of both our group as well as some great helpers from the Conservation Volunteers. The work focused on adding overstorey species (in this case Mountain Ash) to a scrubby regrowth site located along the Grand Ridge Rd.
Several years ago we had planted Blackwood’s on this site with mixed success. Blackwood seedlings are a favourite food of Wallabies. We found that the Chicken wire guards we used back then were not 100% successful in keeping Swamp Wallabies at bay and that they were able to reach the top and nibble the new growth. An application of Sentree (Wallaby Deterrent) helped to give the plants a fighting chance, but most are still quite stunted where as the ones that have got away have reached over 3m tall. Hopefully the new improved guards we used today; which were taller, wider and made of stronger mesh; will see a better success rate. They will also be able to be reused down the track for future plantings. Some of the dead Blackwoods had reached several feet high and then died. They had no roots left, so not sure whether they had been chewed off (by rats??) or maybe caused by the tubes being root bound or just rotting away, the stems were still quite green.
All up we planted 40 new Mountain Ash trees, as well as removing old guards from previously planted trees. Although this may not be a big number, it is a reflection on the careful effort we made to do the job properly and make sure they are well protected, so hopefully, they get the chance to grow into forest giants. Thanks to Pam and David for preparing a delicious barbecue lunch for the starving workers, and also to the Conservation Volunteers for their tremendous support for this event which was an enjoyable and productive day.
