25.01.2022 The Bush is beginning its annual show.

24.01.2022 One of the jobs for last week was a ripline spraying job at Mayfield Road, West Coolup (just south of Pinjarra). The job was spraying an eight metre wide ripped area (except for one 24 metre wide peninsula), around an old quarry which is now a lake, in preparation for revegetation. It would have been ideal boom-spraying job, but it was far to rough, so we sprayed it by hand. The job was a total of 1.4 hectares and every square metre had to be sprayed. We had a team of three rotating through duties. We got the job done in just over 5 hours and used 880L of 1% glyphosate (Biactive) mix. We kept the pressure low at 5 bar to keep consumption down which ended up around 600L/ha. Thanks to Ecojobs for the opportunity, its always good working in new locations and for new clients. Scenery wasn't bad either.

01.01.2022 Landcare Weed Control recently undertook a Nutrient Stripping Vegetation Management Project for the City of Swan at Alta Laguna Park Lake, Ballajura. Alta Laguna Park Lake receives nutrient inputs from stormwater, adjacent deciduous trees and also from water pumped in from nearby Emu Lake. Evidently the nutrient inputs were resulting in water quality issues so measures were taken to remove nutrients from the lake. These measures included designing and installing a clay bund a...rea planted with native sedge species Baumea preissii (Broad Twig Sedge). The bund is located in between where nutrients enter the lake and where the water exits the lake therefore the water has to pass through the vegetated bund where it can be stripped of nutrients. The rationale behind the use of the sedges is that they convert nutrients into growth and also the leaf surface develops a biofilm which also strips the nutrients from the water. The sedges established quickly and within three years had filled the entire bunded area (~600 square metres). A decision was made recently to remove the top growth (biomass) from the vegetation which contained a large amount of dead material. If the dead material is not removed it has the potential to breakdown and add nutrients back into the water. The sedges will regrow from the rhizomes and the nutrient stripping cycle will recommence. A combination of mechanical and manual methods were used to cut and remove the top growth. Approximately 100 cubic metres of material was removed from the lake area. Some top growth was left uncut in the peripheral bund areas as habitat/cover for native fauna including the pair of Pacific Black Duck that reside at the lake.
