Vegetation Management

Landloch’s experienced and accredited technical staff provide a range of vegetation management services, including:

1. Spot spraying of weeds;
2. Broad acre spraying of major weed infestations;
3. Cutting and stump-treating saplings; and
4. Use of chainsaws and brush cutters to reduce vegetation loads.

Site rehabilitation and revegetation

Landloch’s site rehabilitation services include:

1. Soil characterisation and development of fertiliser and amendment recommendations.
2. Design and supervision of surface preparation and erosion control programmes;
3. Recommendations for vegetation to meet site properties and requirements;
4. Fertiliser spreading;
5. Seeding using dozer and RTV-mounted equipment; and
6. Assembly and operation of temporary irrigation equipment.

Vetiver grass

Vetiver grass (Vetiveria zizanoides L.) is a perennial, tropical/sub tropical grass that has been used extensively world wide for soil erosion, sediment control and steep slope stabilisation. Vetiver is now accepted as an important tool for stabilisation of steep slopes and batters in road and railway infrastructure by Queensland Government Departments of Main Roads, Natural Resources and Water and by commercial engineering consultants. Landloch has expertise in the provision, planting and management of vetiver grass, and can ensure that vetiver plantings are successful and effective.

Design and Implementation of Rehabilitation Monitoring

Landloch offers a range of methodologies for assessing success in rehabilitation of disturbed sites. Landloch tailors the monitoring program to individual sites, to ensure that the those factors influencing stability are monitored and that regulatory objectives are met. Landloch uses Ecosystem function analysis (EFA) to assess how well a rehabilitated ecosystem works as a biophysical system. For many constructed landforms, gullying is the dominant erosion process and Landloch’s Geomorphic Gully Assessment System (GGAS) was developed to assess gully activity and changes in activity through time. Digitial photogrammetry is used to quantify volume change of a surface due to erosion, or to measure gully volume. A range of geomorphic factors that increase the risk of future “failure” can also be monitored.
