Wetlands - an integral component of our natural resources.

Limosella Consulting works closely with various specialists to form a team of dedicated professionals in the environmental field.  Although our business is based in Pretoria, Gauteng, we have worked on projects in all the provinces and as far ranging as Lesotho, Mozambique, and Kenya. Our specialty is in providing high quality, financially competitive specialist assessments with the following focus:



To determine the boundary of a functional wetland and riparian area, based on soil, vegetation, and/or terrain unit indicators in order to propose the development layout.

Wetland/Riparian Functional Assessments

To predict the functioning of a wetland/riparian area using standard accepted assessment methodologies, without the need for comprehensive and expensive empirical research.

Strategic Wetland/Riparian Audits

To determine the beneficial functions of outputs produced by wetland and riparian areas in an overview assessment in order to determine the degree to which they should be protected and/or rehabilitated in the light of regional development planning.

Biodiversity Assessments

To conduct a survey or inventory to collect information on the species present in a given a area in order to determine patterns and trends of biodiversity within the area, as well as highlight sensitive biodiversity areas that should not be disturbed by development. Therefore, areas that should be left alone or areas that can be developed with mitigation etc.

are determined.

Mitigation and Rehabilitation

To provide a comprehensive evaluation of practicable alternatives to avoid, minimise or deter the impact of the proposed development on the existing wetland/riparian areas, as well as to enhance wetland buffer functions.

Sensitivity Mapping

To predict and indicate ecologically sensitive areas and resources to inform development layouts on a regional or site specific scale. We work closely with GIS specialists in order to do so.

Projects | Some of the work we have done.

Project: Zola Park ECO (ECO on High profile rehabilitation project)


Description:  To provide a baseline wetland assessment during the first phase of an ECO on a high profile rehabilitation project of Zola Park. This included a detailed wetland delineation, highlighted current impacts and described wetland integrity.


Appointed as Specialist ECO during a second phase. To provide input into the rehabilitation plan, including monthly assessments to ascertain compliance to the Environmental Management Plan, and suggestions as to special attention needed.


An article regarding this project was featured in Landscape SA (March/April 2013, No. 52)

Project: Midrand Powerline Rebuilds (Strategic assessment of regional wetlands and rivers to inform 14 powerline alignments including a general rehabilitation and monitoring plan)


Description: To undertake riparian and functional assessments along the route alignments of poweline sections to be upgraded and constructed in and around Midrand, Gauteng. Implications of the development to the wetlands were also investigated and rehabilitation and mitigation discussed.

Project: Alexandra Pedestrian Bridge (Fine scale wetland/riparian delineation and functional assessment and general rehabilitation plan)


Description: A wetland assessment in order to determine the presence or absence of wetland and/riparian conditions on the study site and assess accordingly; delineate the extent of these conditions, if present; recommend suitable buffer zones; undertake the functional assessment of wetland and/or riparian areas, and; assess the possible impact that the infrastructure and associated activities could have on the watercourse. Mitigation and general rehabilitation measures appropriate to the proposed activities were also provided.

Project: Firgrove substation (Mitigation report focusing on wetlands, but also including fauna and flora)


Description: To conduct a site survey of the proposed Firgrove MTS Substation and Palmiet Stikland Loop (in particular site Alternative A) in order to indicate wetland boundaries and their  associated buffer zones relative to site Alternative A; indicate possible impacts that the proposed activity could have on the wetland(s), floral and faunal components of the biophysical environment; and recommend mitigation measures in order to limit the impact of the proposed development.
