Most fruit and vegetable plants require pollination, yet the honeybees, bumblebees, hoverflies and other insects that carry out the pollination are having a tough time. Habitats are being degraded, reducing the number of nectar-rich plants in built-up areas; while disease, varroa mite and insecticides have taken their toll on honeybee numbers.
The situation can be improved by individuals planting
nectar-rich plant species for feeding insects on an ad hoc basis. However, an
initiative to improve insect pollination services through public participation
has just been launched: the Nectar Point Network.
A nectar point is a location that has been augmented with
plants that produce nectar for insects. It could be in a community garden, residential
garden, school grounds, park, roadside verge, or even a large window-box. A
nectar point network is a coordinated series of such nectar points in a given
area. The network rests on a group of local activists in a growers hub, such as
a community garden, who use their skills and resources to propagate nectar-rich
plants to supply to their neighbours.
The main considerations in establishing nectar points are to
select nectar-rich plants to grow in soil or containers, and to keep a record
of the outcomes of planting and any monitoring of pollinators that is done. There
is therefore an element of citizen science involved in nectar point networks,
with participants encouraged to learn about different pollinator species (e.g.,
bumblebees) and to communicate their
findings to other groups (e.g., via websites and blogs).
Networks of nectar points can be planned to create ecological corridors through built-up areas for pollinating insects, and to generally enhance local biodiversity and wildlife in gardens and streets. Networks can also, of course, encompass apiaries, and the strategic location of bee tubes or hotels for solitary bees species.
Here are some bee-friendly plants for gardens: heathers, rosemary,
dead nettles, pussy willow, thyme, cotoneaster, wallflower, sage, honeysuckle,
comfrey, cornflower, buddleia, delphinium, hollyhock, and lavender.
The Nectar Point Network website suggests several local actions for
groups. ‘Linking with Lavender’ is one example of a
neighbourhood growing scheme with the objective of establishing nectar-rich plants for pollinators in an urban setting. It relies on a local community garden acting
as a hub for propagating and distributing plants in pots to its
neighbours. The pots can be returned to
the hub annually or purchased. Costs
could be met by local sponsorship. The pots, containing lavender or any other
nectar-rich plants, can be used on patios or paved front garden.
A Welsh Government draft Action Plan for Pollinating Insects
was launched in July 2013 (see below), in recognition of the major economic importance of natural pollination services. Also, a new Welsh Government initiative
called Cynefin (meaning ‘habitat’) aims to help individuals and groups
throughout Wales mount community-led environmental action plans. Cynefin
Cardiff is already working with four community gardens in Cardiff with a view
to starting a city-wide Nectar Point Network.
This should be the first of a series of posts on Nectar
Point Networks on this blog, as I help get a network hub started here in Dinas
Powys. I will report on what is involved, and write more about schemes to
improve the pollination of fruit and vegetable plants, during the year.
