Short description of the intervention
Ngong is a town in southern Kenya, located near Nairobi in Kajiado County, on the slopes of the Ngong Hills. The municipality has experienced significant development and population growth due to improved infrastructure and social amenities. However, this expansion poses a threat to biodiversity, as increased demand for agricultural land, wood, and raw materials is depleting the area's forests and putting many species at risk of extinction. Overgrazing, illegal logging, invasive species, and climate change-induced extremes like droughts and floods have further exacerbated the situation.

In response, the Rufford Foundation proposed the Improving Ngong Hills Forest Conservation Efforts through Raising Local Community Awareness of Biodiversity Conservation project. The initiative seeks to restore the Ngong Hills forest ecosystem through community-driven conservation. A nursery for native species was established, and tree planting campaigns were conducted in collaboration with national and local governments, community-based organizations, indigenous groups, and schools. Additionally, awareness programs and capacity-building efforts were launched, engaging local schools in restoration activities and organizing workshops to train community members and officials.

Implementation activities and NBS focus
Implementation activities
The project began by collecting baseline data, including vegetation surveys, land use changes, and community perceptions of biodiversity threats (Ref 2).
Restoration efforts in Ngong Hills included:
Seedling propagation: Community nurseries produced 9,000 seedlings of indigenous species (Ref 2, 4).
Reforestation: Over 9,000 native trees were planted using techniques like Miyawaki to enhance biodiversity, with schools participating in tree planting and education (Ref 2, 3).
Invasive species management: Surveys were conducted to assess and address invasive species removal (ibid.).
Livestock grazing management was tackled through collaboration with communities, promoting sustainable practices like fodder cultivation and agroforestry (Ref 3).
The school-based restoration program engaged schools like Uppah Matasia and Nalepo Primary, resulting in the planting of 300 trees, with students taking responsibility for tree care (Ref 2).
To raise awareness, the project provided workshops and training to over 800 locals and 30 trainers, focusing on biodiversity conservation and nursery management. Pre- and post-training surveys tracked participants' knowledge and attitudes (Ref 2, 4). Marginalized groups, including women, youth, and elders, participated in training workshops and capacity-building initiatives, gaining skills in conservation practices, seed collection, and nursery management, while ensuring their voices were heard in decision-making (Ref 2, 3, 4, 5).

Barriers
1) Unforeseen difficulties stemming from the impact of climate change on weather patterns (Ref 5):
- Seed planting affected: "Delayed rains and prolonged dry spells affected the project's schedule, hindering mapping and seedling collection efforts. ...Subsequently, when rainfall did arrive, it exceeded average levels, leading to flooding and landslides";
- Interaction with schoolchildren delayed: Interaction with schoolchildren within their institutions was also delayed due to weather changes, impacting tree planting activities. Furthermore, a lack of water in schools hindered the watering of seeds".
2) Incorrect community perceptions: "...as some community members mistakenly believed there was direct monetary benefit associated with the project, leading to false and exaggerated information" (ibid.)
3) Water scarcity: "The main challenges associated with planting indigenous trees included water scarcity. To address these challenges, various solutions were proposed. These included harvesting and storing water during the rainy season, training on sustainable methods of watering trees during dry periods (such as using recycled bottles as makeshift irrigation devices)" (ibid.).

Impacts, benefits
Description of environmental benefits
-Expected improved resilience against landslides: "The consequences of deforestation extend to the soil, once shielded by the extensive root systems of the forest flora. The eroding topsoil and the looming threat of landslides stand as direct outcomes, highlighting the profound impact on the land's fundamental foundation as the trees' protective mechanisms diminish. " (Ref. 4)
- Improved soil quality: "Their roots also stabilise the soil, create pore spaces for water infiltration, and access groundwater, thereby reducing water table levels and preventing excessive water loss through runoff" (Ref 2);
- Increased conversion of degraded land or soil: "This area, once cleared due to deforestation, has now been revitalised through our strategic reforestation approach" (Ref 3);
- Reduced biodiversity loss: "Forest biodiversity was maximised through the selection of suitable areas and species" (Ref 5);
- Increased number of species present: " Through partnerships with local agencies and communities, over 9,000 trees were planted" (Ref 2); " Implementing the Miyawaki method introduced 10 distinct tree and shrub species, ensuring a diverse and resilient ecosystem" (Ref 3);
- Increased spread of native/heirloom/open-pollinated seed: " Here, we established the first community nursery in Ngong Hills and produced over 6000 seedlings for planting and restoration" (Ref 5); "The selected plant species for restoration in Ngong Hills encompass a diverse range of indigenous trees, each contributing uniquely to the ecological richness of the region. These include Olea capensis, Warburgia ugadensis, Prunus Africana, Croton megalocarpus, Vitex kenesiensis,
Cordia Africana, Markamia lutea, Acacia xanthophlea, Verchellia Seyal, Olea europea and Vepris. Given the open nature of the restoration area characterized by minimal canopy cover, approximately 3%, a strategic decision was made to prioritize pioneer species. These species, known for their rapid growth and horizontal development, play a pivotal role in providing
substantial shading. Additionally, special consideration was given to the selection of droughttolerant species, with a focus on trees such as Vepris spp and Verchellia spp. These species exhibit resilience in challenging environmental conditions, particularly in dry and hot climates. " (Ref. 4)

Over 9,000 trees planted, 10 distinct tree and shrub species introduced, over 6,000 seedlings planted
Description of economic benefits
- Increase in agricultural production (for profit or not): "During the conservation training, we emphasised agricultural practices, including grafting lemon trees to improve quality and production" (Ref 5);
- Generation of income from NBS: " By collaborating with local communities, the project has not only contributed to
preserving the environment but has also generated income and sustained the livelihoods of local communities" (ibid.).
Description of social and cultural benefits
- Increased visibility and opportunity for marginalised groups or indigenous peoples: “We also prioritised working with representatives of FIVE local community-based organisations, one national group, and the local government representatives including two chiefs, four Maasai community elders and six Kikuyu community elder representatives to ensure we reached more people“ (Ref 5);
- Increased involvement of locals in the management of green spaces: "The project engaged various primary stakeholders, encompassing individuals, local communities, and community groups, alongside secondary stakeholders like academic and research institutes, as well as donors and funding agencies" (Ref 2);
- Increased awareness of NBS and their benefits: "over 800 locals (mostly interacted with during the mapping and planting exercise) were made aware of the importance of the conservation of Ngong hills"; “Their new found awareness has led to a change in their attitudes and behaviour towards the environment, making them more environmentally conscious. Moreover, they have developed a sense of ownership and responsibility towards the forest, leading to an increase in community participation in conservation efforts” (Ref 5).
