Quickening Ecological Restoration On St. Kitts

May, 2024. UNESCO. On International Day for Biological Diversity, we highlight the remarkable efforts underway to accelerate ecological restoration at St. Mary’s Biosphere Reserve on the island of St. Kitts. Home to thousands of species, this UNESCO-designated site spans vast marine areas, forested ridges, agricultural hills, cloud forests, mangroves, and coral reefs. Despite its rich biodiversity, 32% of the land is degraded, necessitating urgent restoration efforts. St. Mary’s is the first site to benefit from the expertise of volunteer scientists from the UNESCO Earth Network project, aimed at collecting key data, implementing restoration plans, and identifying sustainable livelihood opportunities.

St Mary’s Biosphere Reserve’s main challenges

Like many Caribbean islands, the socio-economic history of St Kitts and Nevis was marked by a heavy dependence on the lucrative sugar trade. Thanks to governmental efforts to diversify the economy since 1970s, the federation turned to tourism development, which brought unprecedented opportunities to improve the livelihood of locals. However, when the tourism industry came to a near standstill between 2020 and 2021, St Kitts and Nevis saw a 14.5% drop in its GDP, followed by another 4.3% contraction in 2021.

In addition, as a Small Developing State (SIDS), it faces a number of natural challenges accentuated in the last decade by climate change, with more frequent and violent natural disasters, including hurricanes and seismic events. The effects of climate change highlight the need to protect tropical forests and promote resilient and biodiversity-friendly agriculture.

What does agriculture have to do with biodiversity conservation?

One of the primary goals of St Mary’s Biosphere Reserve is to conserve biodiversity, particularly one of the most emblematic species of the area, the critically endangered leatherback turtle. It may not seem obvious, but this goal is closely related with sustainable agricultural practices.

As explained by Dr Kimberly Steward (Ross University), leachate and chemicals used in farming end up on the beach and affect nesting zones as well as the algae, food and refuge for the leatherback and other turtle species.

What were the objectives of the UNESCO Earth Network mission to the biosphere reserve?

With the generous support of the Government of Italy, the Earth Network project embarked on a mission to St. Mary’s Biosphere Reserve site to promote and work on ecological restoration. The initiative addressed specific challenges associated with agricultural practices, tools and methods of the St. Mary’s Biosphere Reserve site: cultivation, preservation and monetization of sustainable and biodiversity-led agriculture processes.

Furthermore, an inventory of biodiversity loss, i.e., soil-erosion, tropical forest depletion, diminished mangrove cultivation, extent of fauna and different species of birds, bees and other pollinators etc., was prepated. The mission also analysed potential employment opportunities based on sustainable, biodiversity-friendly agriculture practices and tools, i.e., better use of tropical forests as sources of new fruit and vegetable cultivation, and introducing new seed varieties more tolerant to heat and drought; and examined opportunities for the creation of small enterprises associated with sustainable use of natural resources and biodiversity.

Development of the mission and its first achievements

The mission was conducted in two phases, both led by volunteer expert, Dr. Haydi Berrenstein. The first field mission took place from 20 – 24 February 2023 to collect data, assess the situation and exchange with local experts, as well as to interview local stakeholders.

A second mission took place in August 2023, when the Earth Network volunteer expert and local community members worked together to formulate technical advice towards an ecological restoration plan in line with available good practices and assess the feasibility of a local biodiversity inventory.

Additionally, in August 2023, a plan to improve their practices began to be implemented, through the creation of a Seed Bank, the development of natural fertilizers and a whole Biodiversity Agricultural Reforestation plan. The overall aim is to embrace better use of tropical forests, enhance the cultivation of new fruits and combat soil erosion.

Furthermore, the knowledge generated through the mission was consolidated and included in the UNESCO Biodiversity Portal, which provides real-time data from UNESCO-designated sites, as well as top-notch solutions.

Toxic Algae Blooms in Lake Erie Cause Water Emergencies

Lake Erie toxic algae bloom causes water emergency in Toledo, OH -citizens scramble for bottled water http://patch.com/michigan/novi/lake-erie-toxins-leave-southeast-michigan-ohio-residents-without-water#.U94tq7fD_IU#Silo #Earth

It doesn't take a lot of imagination of smarts to understand that toxins can travel in water. Ohio and Southwestern Michigan which have notified the public of the water crisis are dangerously close to other Lake Erie shoreline communities. Some communities such as Norfolk County already have beaches posted with bacteria warnings and notices that the water is NOT tested by local health officials.

Watershed Forests Returning On Former Farmer Fields

The Grand River watershed was 85 per cent forest 200 years ago. However, tree cover dropped to just five per cent by 1900 as land was cleared for farming and urban areas. Today, the tree cover has rebounded to about 19 per cent. Environment Canada suggests a healthy watershed needs a tree cover of about 30 per cent.

Today, the tree cover has rebounded to about 19 per cent. Environment Canada suggests a healthy watershed needs a tree cover of about 30 per cent.

New forests are rising on old farm fields in Mapleton Township  in an effort to improve water quality in streams feeding Conestogo Lake reservoir.  About 70,000 trees are being planted this year and next on two parcels of land totalling 40 hectares (100 acres) on the north side of the reservoir.

The GRCA is planting a variety of species that are native to the area, including spruce, tamarack, white pine, bur oak, silver maple and cottonwood. In addition to the new forests, the GRCA will also do some reshaping of the landscape to create some seasonal wetlands that will also help improve water quality and provide additional habitat.

As the trees grow in coming years, the areas will quickly become home to a variety of animals, such as deer and wild turkeys. Later, as the forests mature, it’s expected that several bird species including scarlet tanagers, ovenbirds and great horned owls will take up residence. A 12 hectare parcel near Wellington Road 10 and Concession Road Five has been planted this year. The second parcel of 28 hectares is near Concession Road 5 and Sideroad 15. About 18 hectares has been planted this year and the rest will be planted in 2015. The land was acquired by the GRCA when it built the reservoir in the 1950s. It has been leased to farmers since then.

These two parcels of land were prone to erosion which sent a lot of sediment down the streams into the reservoir, explained Ron Wu-Winter, watershed forester with the GRCA. In addition, the sediment also carried nutrients – phosphorous and nitrates – which are found in manure and commercial fertilizers. The nutrients would spur algae and plant growth in the reservoir, resulting in lower water quality.

The northwestern part of the Grand River watershed contains some of the best farmland in Ontario. As a result, the forest cover is some of the lowest in the watershed. Forest cover is estimated at 15 per cent or less. A healthy watershed should have forest cover of about 30 per cent. Trees help raise water quality in several ways. They soak up nutrients in the soil, so reduce the volume that runs off the surface into a watercourse. Trees along a stream shade it, keeping it cooler in summer which is good for some coldwater fish species.

The total cost of the project is about $150,000. About $50,000 was contributed by the Grand River Conservation Foundation. It is also supported by the Trees Ontario Foundation which is contributing $65,000. For the Silo, Dave Schultz.

Tree Facts
* Across the entire watershed, the GRCA will plant about 400,000 trees this year, including 95,000 on its own land and 300,000 in partnership with private land owners.
* The GRCA operates a nursery near Burford, in Brant County, where it grows more than 150,000 trees a years from 60 different species.
* Since it was created in 1934, the GRCA has planted more than 27 million trees on both private land and its own land.
