The primary objective is to eradicate localized populations of invasive alien plant species, specifically Cylindropuntia pallida, across Bethulie Town and Orange River Guest Farm in the Northern Cape and Free State regions. Early intervention aims to prevent further ecological spread, reduce long-term management costs, and support national biodiversity conservation targets through systematic detection and removal.
The successful service provider will deliver clearing operations over a two-year period (2026–2027 and 2027–2028). Key activities include surveying designated localities, physically clearing all listed invasive plants, and collecting precise GPS and ecological data. If work concludes ahead of schedule, the contractor must adapt to additional species or newly identified sites. All operations are monitored by SANBI and landowners, with corrective clearing required outside the contract term if standards are not met.
Payment operates on a person-day basis, meaning compensation is strictly tied to days worked rather than a fixed salary. Should milestones be completed early, SANBI reserves the right to assign supplementary conservation tasks to utilize remaining person-days. The contractor must ensure at least 60% of the workforce comprises local beneficiaries from the target areas.
Bidders must demonstrate compliance with statutory, safety, and operational standards:
The contracting entity must deploy a physically fit, trained team of ten members with proven field experience:

Most large tenders are composed of tasks in a number of different fields, and it is not always possible for a single company to cater for all of them, and therefore Joint Ventures and Consortia are formed to then submit a tender together.
Government tenders are also requiring the subcontracting of a percentage of the tender work, and the trouble is then finding Subcontractors to comply with the tender requirements
To assist companies with finding tender partners and subcontractors, you can now submit your contact details and company information on this page, so other interested parties can contact you for purposes of forming Joint Ventures and subcontracting
