At our last meeting, David Owen from ECan presented ECan’s aims to work with communities and landowners to restore and protect 10 key braided rivers in 10 years (well, 9 now). The Ashley Rakahuri River is the first of these, in part because of the strong and well-documented record of bird counts, trapping results, and relationships between weeds, gravel extraction, and nesting preferences and successes. And in part because a landowner upriver of the group’s primary ‘workspace’ is keen to see how weed removal will help improve the river. This underscores the vital role of citizen science being undertaken by community groups, and the importance of engaging with other members of the community to improve our waterways. Work is already underway on the river, and we look forward to updates.
The Orari River Protection Group also presented at the meeting, on the work they’ve been doing to protect colonies of black-billed gulls and black-fronted terms on the river…a river, I might add, so glutted by weeds its braids have been severely restricted. Nevertheless, their dedicated trappers and some fortuitous work by gravel extractors led to a surprising and very gratifying outcome for the birds. You can read both reports here (scroll down to ‘Bird Surveys’ : 2019).
