Bees today

MY Bee Savior Association is an NGO that was established in 2015 to create public awareness of the importance of bee sustainability. It also aims to strengthen the efforts to increase bee populations and to empower corporate commercialisation in the field of bee keeping. Bees are highly important for crop pollination. These bees include Apis mellifera (western honey bee), native to Europe, and Apis cerana (eastern honey bees) which can be found in our country. They are highly managed in hives for crop pollination.

Populations of these agricultural pollinators are declining worldwide. This phenomenon, known as Colony Collapse Disorder, occurs when the majority of worker bees disappear. It first came to the world’s attention with reports of western honey bees disappearance in North America in 2006.  But most beekeepers in European countries (especially in Northern Ireland) experienced a similar phenomenon in 1998, where there was a reported decline of 50% in bee population.

Now, this phenomenon has become global and affects some Asian and African countries as well. This shows the great need to protect, conserve and preserve our bee populations. We have to start worrying now before it is too late. 

The possible causes of Colony Collapse Disorder include climate change, non-native species presence, pesticides and genetically modified crops. Discontinuous supply of flora resources, disease and habitat fragmentation all play a role in the decline of bee populations.

Bees need us. How can we help them?

From the perspective of a landscape architect, one of the ways which can help restore bee populations and preserve their habitat is establishing bee gardens. Cities hold the key to saving bees because cities encompass urban green spaces (UGS), for example, green roofs, public gardens, community gardens, allotments, domestic gardens, etc. The ability of these places to support biodiversity has been recently acknowledged. There is now a call to effectively integrate these UGS in biodiversity planning and management to ensure their full inclusion in biodiversity conservation.

The urban garden is one of the UGS that we are concentrating on now. It is preferred by bees because of the wide range of fruits, vegetables, flowers that can be found in the garden. Many studies find that urban gardens often attract up to ten times more bees than the places we might consider bee havens such as nature reserves, parks, cemeteries and other public green spaces. This is because bees are unable to thrive when there are only trees or turves. Thus, we should try to plant a variety of flowering plants that are richer in pollen and nectar.

Bees provide flowers the vital service of pollination, help us to produce healthy crops and maintain thriving ecosystems, which in turn ensure our health. In simple words, bees are important for the overall health of the environment.

Urban bees

Here are some of the bees that can be found in our cities:

  • honey bees (lebah madu)
  • stingless bees (lebah kelulut)
  • solitary bees (lebah tunggal)
  • bumblebees (lebah dengung)

(among the four types of bee, the bumblebee is perhaps the most glamorous because of the movie Transformers)

Establishing bee gardens in the city

Bees are unique insects. They play a major role in plant pollination due to their absolute dependence on flowers as their source of food. Therefore, bees that live in the cities seek out green spaces like parks and gardens. These green spaces in urban areas provide a proper habitat to the bees, thus helping in the conservation of bees.

When designing a bee garden, the flowers have to be in large patches because these would allow bees to dine at one spot for a long period of time. Otherwise bees would expend too much energy flying from one location to another, leading to stress. In one spot, we ought to have more than two species of plants. Researchers suggest a minimum of ten species of plants to be planted in one spot.

When there is limited space, a vertical bee garden can be one solution. We can use walls or trellis as media to hang the plants. We can also make cool ponds for bees to take water, adding features like pebbles in the water so the bees have something to land on and do not drown.  

Typology of green spaces for bee gardens

There are many types of green spaces in the city. When considered collectively as wider infrastructure, they can create extensive and powerful recreational, cultural or community spaces and improve environmental quality as well as provide diverse and species-rich habitats.

Urban squares attract urbanites to get together and socialise, why not extend this function to let bees to have fun as well? By planting a variety of trees and plants in the planter boxes, and establishing green roofs at the gazebos, we can make urban squares key sites for conserving bee populations. 

Bioswale or rain garden can be turned into ‘Beeswale’ gardens. While managing the stormwater, we can also take care of urban bees.

Vertical walls have an amazing and dramatic appeal. These walls are popping up in major cities all over the world. A large vertical wall can be covered by hundreds of plant species which are good for bees.

Bee pop-up gardens can be established anywhere in the city, even at the roadside or in parks. They beautify the environment while providing foraging habitat for bees in the city. One of the pop-up gardens in Sweden comprises hexagonal structures which act as planting vessels that contain plants and water. These gardens can be incorporated into edible gardens as well.

Other places include rooftops, residential gardens and small individual gardens.

The landscape structure of bee gardens

To sum up, the basic elements for creating bee habitats are softscape, hardscape and water features.

Softscape refers to a composition of native plants with varieties of bee-preferred species. These plants should have flowers that are rich in pollen and nectar. It is good if the plants flower all year round. The plants also have to be intensely fragrant and have vivid colours. Some choices include Cosmos caudatus (ulam raja), Portulaca grandiflora, Angelonia spp, Antigonon leptopus (coral vine or air mata pengantin), Jasminum sambac (jasmine), Nelumbo nucifera (lotus).

Hardscapes or hard structures such as planter beds, boxes or vertical walls support the plants. These structures are useful when you have limited garden space. We can also construct bee houses or bee hotels for solitary bees to rest, lay eggs and raise their young. Although these bees do not produce honey, they are excellent pollinators.

Water features provide fresh water for the bees.

Biodiversity Gardening

from Biodiversity Gardens Capacity Building Workshop with Tan Kai Ren

Tan Kai Ren was the project officer of the Rimba Project in University of Malaya where he conducted a series of urban biodiversity conservation and education programmes. He also organised the Klang Valley City Nature Challenge in 2019, a citizen science project that focused on collecting biodiversity data in the urban area. A former YSEALI Academic Fellow for Natural Resource Management and Environmental Issues, he is now an environmental officer at Club Med Cherating.

Kai Ren discusses how we benefit from biodiversity and how we can introduce elements that promote urban biodiversity.

Importance of biodiversity

Biodiversity provides us with oxygen and food, a fact that many of us seldom appreciate as we do not see the link between nature & human. It helps increase productivity as diverse soil microbes are involved in nutrient cycles where they break down organic matter underground and keep plants healthy.

Biodiversity also contributes to our health. Many pharmaceutical products are made with raw materials that come from many different plants in the forest. It contributes to our economy as well: places with high biodiversity become recreational destinations and attractions for tourism.

Biodiversity contributes to pest control too as it regulates the number of pests by natural processes through prey and predator interaction.

The keys to high biodiversity in your garden

High number of plant species results in high diversity of features and micro-climates that promote different kinds of wildlife. For example, companion plants grown alongside desired garden plants distract insect pests. This helps targeted plants grow more successfully.

Selecting local plant species for your garden attracts local animals as they seek their preferred food.

There is an easy way to look at how local wildlife can improve our life quality. The plants and animals such as the mammals, insects and birds in our garden interact among one another, forming food webs that regulate the population number of each species, including pests.

Many people think that more plants will attract more mosquitoes. In fact, once a whole ecosystem is established, there will be fishes eating the mosquito larvae and dragonflies eating the mosquitoes. As a result, less mosquitoes are found in the place.

The roles of a garden as a habitat

As urbanisation takes place, land that was covered almost entirely by natural forest habitats is replaced by high-rise buildings, roads and houses that lead to habitat fragmentation. Some animals find it difficult to survive in such conditions, especially those that need large spaces, e.g. elephants, tigers and other large mammals. Animal populations end up being threatened, some may become locally extinct, even the so-called common or urban species.

To re-introduce wildlife into our city, we can start growing fruit trees and wildflowers in our garden, as these plants attract butterflies and birds. We can view gardens as a shared space for ourselves and the wildlife. When we establish a balanced ecosystem in our garden, our garden serves as a place for animals to rest, nest and feed. Perhaps it is not for the relatively large animals, but the garden is still friendly to smaller and more mobile animals that contribute to the food chain.

We can view gardens as a shared space for ourselves and the wildlife.

We can try to make our gardens a bit wilder so as to attract wildlife such as the monitor lizard, bats and the Asian tree toad. Sometimes, when biodiversity comes to us, we push it away for reasons like guano from bats, for example. However, we can still try to find a solution to overcome these problems.

During the Klang Valley City Nature Challenge, over 2000 species of plants and animals were documented in Kuala Lumpur despite its urban setting. Urban gardens play a large role in supporting wildlife. Therefore, anyone can contribute to wildlife conservation, even in the city, by just growing a single plant in his or her garden.

Elements to encourage biodiversity

  1. Sunlight. The essential element that plants can’t live without but there should not be too much exposure.
  2. Shade. Shade is especially important for certain plants such as moss, ferns and orchids.
  3. Water. Both continuous supply and temporary puddles are important to wildlife. Water features will attract frogs that eat mosquitoes.
  4. Hideouts. The small lizards and frogs need these dark spaces, whether they are natural or artificial.
  5. Plants. Have more plants that attract pollinators such as bees, butterflies as well as birds. The selection of plants depends on our expectations and objectives. Arrange plants in multiple layers to create spaces for shade-loving species. It is important to know the growing requirements of the plants. Choose plants that flower and fruit all year round. These plants are best for wildlife.
  6. Decaying materials. Compost, logs, mulch that consists of dry leaves or wood chips increase biodiversity underground and keep plants healthy.
  7. Feeding station. Provide grains for birds.

Ideas for a wildlife garden

  1. Build an insect hotel by piling branches or rocks to create a moist and dark space for the insects.
  2. Mulch plants to attract beneficial insects and earthworms that help release nutrients back into the soil. This will also attract more birds e.g. the wild junglefowl.
  3. Create a small pond using plastic bottles or trays. Insert fish to inhibit breeding of mosquitoes. Small ponds help to increase biodiversity despite their size. It is also a good place for dragonflies to lay eggs.
  4. Start composting. We produce food waste every day. The fruit peels or roots of vegetables can be turned into compost that help gardens grow.
  5. Limit the use of insecticides as the toxins will cause long-lasting effects on non-target insects. Try alternative methods e.g. hand removal of the pest insects.
  6. Plant fruit trees as most of them are perennial. Besides, they bear edible fruits for humans and animals.

Knowing your limits

Knowing the right microclimate is especially important for plants such as orchids and leafy vegetables. Also, make sure there are enough spaces for the plants to grow. The intensity of sunlight is a decisive factor for plant growth. We also need to have the suitable soil type to produce healthy plants that support wildlife.

Most importantly, make sure you have enough time to manage your own garden. More is not always better as nature can be messy sometimes. It is always about balance. Avoid dominance in terms of plants as well as animals.

Biodiversity in Cities

plant shoot road

In recent years, ecologists have begun to take a second look at plants and animals appearing in cities. There seems to be more ‘nature’ in urban areas than one would expect. Cities are supposed to be human territories—steel, brick and concrete—not exactly welcoming to wildlife. But urban places display a variety of species and habitats – biodiversity—in places we did not plan for them.

This makes us ask some questions:

Why are these plants and animals surviving in human settlements while others disappear? How and when did they move in? How many of them can survive in our cities?

Urbanized areas often share characteristics like:

  • hard surfaces (roads, pavement)
  • roads and buildings that break up natural, vegetated spaces
  • bright light at night, loud sounds, water and soil pollution

All of these are known to make it difficult for ‘natural’ habitats to survive near cities.

But there are also ‘built’ green spaces like public parks and private gardens that cultivate a wide range of native and exotic plants. These can form the bases of food chains that attract consumers (like ants, grasshoppers, bees, beetle, squirrels) and their predators (lizards, birds, and monkeys), without our approval. If left uninterrupted, patches of wild ecosystems can be established within these built spaces.

But exactly which species of birds, bees and trees settle in cities? Where in a city are you more likely to come across wildlife? And, how come I can see kingfishers in one district but not another?

Another attribute of cities is the diversity of the habitats (or shelters) they can, unintentionally, form. Within one city, you can find

  • abandoned lots-turned-grasslands
  • waterways
  • old buildings that create dark and cool shelters
  • long stretches of roadside vegetation
  • food gardens
  • golf courses
  • remnant forests

Each of these will have unique structural features, creating different kinds of habitats.

For instance, reptiles that inhabit open spaces within their original forest habitats will probably adapt well to places in cities that have widely spaced trees and vegetation.

Wildflowers too benefit from the abundant sunlight and absence of competition (bigger plants) in urban patches. These are conditions not found beneath dense, natural forest canopies.

A more familiar example is the ubiquitous city pigeon. Have you ever wondered why this bird in particular flocks in cities worldwide? One reason might be the similarity between its original habitat – rocky cliffs – and the hard, ledged surfaces of city buildings that offer it space for nesting.

There is also another feature of cities that might be important for supporting biodiversity – the greater amount of food available. For species that are not very particular about their diet, gardens, cafeterias, litter, bird feeders, ornamental trees and nutrient-rich waterways offer abundant food resources.

So what does this mean for us?

One reason that ecologists are interested in urban wildlife is the benefits associated with biodiversity.

In natural ecosystems, there is abundant tree and vegetation cover, and processes like pollination, seed dispersal and decomposition that are carried out by large and small animals. All of these contribute services like food production, climate and water supply regulation.

These benefits (also known as ecosystem services) are important for us. If cities can support biodiversity, then they can help in species conservation and contribute these services that keep our environment healthy.

Urban biodiversity still poses many questions for ecologists to explore.

  • How much green space is enough for biodiversity conservation?
  • What ecosystem services can we expect from urban biodiversity?
  • How are urban plants and animals different from those in natural habitats?
  • How and why do biodiversity patterns vary among cities and geographical regions?

Answering these questions will take time and require that we pay closer attention to the other lives unfolding parallel to ours.
