Initially these activities were pursued with limited funding from LIRA, Gardening at Leisure (the Island garden club), a municipal grant and ad hoc donations. The indigenous and entrance gardens were completely revamped and regularly maintained. Timber pole fencing was restored, an alien eradication programme established and a partly successful dog litter programme implemented with plastic bags dispensers and bins. New indigenous flower beds were introduced, many of the untidy wild areas cleared and careful pruning of indigenous trees and shrubs undertaken to discourage ‘over-nighting’. Great quantities of loose bricks, glass, plastic and other debris were removed from the salt marsh area inside the Steenbok sea wall and the inlet pipe manhole cleaned up. As a result there is improved tidal flow through the inlet pipes and the salt marsh area inside the wall is spreading. Great strides have been made with the identification of flora and fauna.
With the advent of Friends of Steenbok and the enhanced funding that this produced, these goals could be pursued more aggressively. Planning and consultation with a broad spectrum of professional advisors, individuals and organizations was undertaken. These initiatives included a geographical survey of the area and detailed examination by a hydrologist and professional engineer of the pros and cons of creating an opening in the Steenbok sea wall to permit an increase in the daily tidal flow into the Park. As a result of valid concerns raised this aspect of the development plan was deferred indefinitely. Tide levels are measured and recorded and indicate that abnormally high spring tides (experienced every five years) can be as much as 500mm higher than predicted levels.
In September 2008 a formal Landscape Management Plan for Steenbok Park (the area east of the Harbour Road) was prepared by Di Grant of environmental planners Grant Johnston Associates. At about the same time Nigel Wessels (previously with Cape Nature) was appointed Vegetation Management consultant for Kingfisher Creek (the area west of the Harbour Road). These plans and recommendations were adopted and were in the main put in place over the following two years. Subsequently advice was obtained from Andrew Johnson of GCS Consultants who also undertook the EIA, for the brick pathway and boardwalks, and obtained the approvals, and who at a later date advised on vegetation and new pathways at Kingfisher Creek. Subsequently annual Action Plans have been formulated and approved by MANCOM in September each year. During this period close relationships with SANParks, Cape Nature, Knysna Environmental Forum, and environmentalists of the Knysna Municipality have been maintained and support and advice sought on an ad hoc basis.
The primary objectives of these plans was to retain the existing very attractive open character; maintain a high species diversity in the natural areas; and at the same time increase its recreational potential. The varied character of the Reserve was enhanced by increasing the diversity of local plant species in the coastal fynbos and dune thicket areas, as well as by the gradual replacement of exotic trees with local indigenous trees. Enhanced biodiversity was achieved by the replacement of exotics with indigenous species, the addition of thorny species to the dune thicket and by increasing the species diversity of the coastal fynbos. Recreation potential was increased by improving access for wheelchair users with the brick path while the new boardwalks now enable comfortable access over salt marsh and wetland in the Park. Interpretive signage relating to the restoration of the coastal and salt marsh, the estuary, and Leisure Isle hydrology was introduced and the display boxes at the three main entry points established to feature seasonal information and news items.
ObjectivesThe objectives set out in the KM/LIRA agreement are still considered appropriate:
- Manage the eco system of the property on the northern shores of Leisure Isle for the benefit of all the Knysna residents, and its visitors, to ensure the natural heritage of this area is nurtured and protected for the benefit of the current and future generations.
- Nurture and protect this area of natural beauty and interest on the northern shore of Leisure Isle
- Create and maintain a place of enjoyment for all whilst recognising the protocols that are applicable in nature conservation areas
- Maintain and establish representative plant communities as found in similar eco-locations along the garden Route
- Protect plant life indigenous to Leisure Isle and the salt marsh community.
Existing Assets and AchievementsSNR is now well established and popular with the public. Assets and achievements are;
- Open vistas, wide skies, feeling of space; and varied views within and beyond the park
- Diversity of vegetation and wildlife habitats:
- Natural dune thicket
- Salt marsh and wetlands
- 2 Klm coastline within the Knysna Estuary
- Indigenous Garden containing botanical species from the Garden Route and Eastern Cape
- Tree copses featuring Knysna forest trees
- Coastal fynbos with many indigenous plants including Satyrium princeps and Brunsvigia orientalis
- Prolific bird and butterflies species.
- Signage identifying the more common plants and trees
- Well positioned directional signage and limited, but interesting information signage and notice boards
- Recreational areas catering for diverse activities
- Accessibility to, and within the reserve on walkways and boardwalks
- Working water hand pump explaining the fresh water aquifer present under Leisure Isle
- Excellent relationships:
- Friends of Steenbok with membership open to all
- Major stakeholders viz Knysna Municipality and Leisure Isle Resident’s Association
- SANParks and Cape Nature
- Website www.steenboknaturereserve.org.za providing comprehensive coverage of all aspects of the Reserve
- Educational boma and support from local schools
- Known and respected brand
- Close working arrangements between Trustees and management and operational committees.
ProblemsSome problem areas include:
- Invasive grass species, which if unchecked will lead to loss of flora and fauna diversity
- Illegal bait collecting off the shores of the Reserve
- The wetland (west of the sea wall access boardwalk) which is not natural; neither salt marsh nor fresh water wetland
- Large numbers of dog walkers do not utilize the plastic poo bags and litter boxes provided.
Landscape MaintenanceThis part of the plan is arranged under the major vegetation zones occurring in the Reserve as fully detailed in the Map featured separately.
