Sheep (C2)

Flock of sheep as an urban non-mechanic vegetation control and soil conservation agent

This action aims to maintain a flock of sheep as a natural (non-mechanical) agent to control vegetation and improve soil quality.

Associating animal grazing with the maintenance of green infrastructure, in addition to reducing human effort and energy consumption associated with traditional mowing, also contributes to boosting pasture ecosystem services. The use of the flock of sheep allows an increase in the organic matter of the soil, increasing its relative humidity, thus contributing to the stabilization of the soil and control of the rate of erosion.

The reduction in energy consumption also contributes to the reduction of C02 emissions.

Although the place where the sheep stay is located in the Parque da Bela Vista, transportation to other green areas of the city is planned.

This action, innovative in an urban environment, requires an evaluation of the results to determine its viability and benefits for green infrastructure.

The costs of this action represent 14% of the total project budget and the following tasks are planned:

  • Installation of a support structure at Bela Vista

To ensure the safety and viability of this action, there is a need for a support structure to keep the sheep overnight, support daily management, and also to support some dissemination/awareness activities.

  • Sheep grazing in Bela Vista Park

The daily management of the flock in a public space requires a specialized shepherd service that can also provide information about the project and importance and advantages of using the flock in green spaces.

Fences are placed to ensure the safety of sheep and citizens (visitors).

  • Sheep grazing in other green spaces

It is also planned to transport the sheep to other areas with meadows, namely in the Alto da Ajuda park. In these cases, the flock is transported to places to graze during the day, returning at dusk to Bela Vista.

Timeframe: start of the installation of the support structure at the end of 2020; testing phase to use sheep starting in late 2020.
