They Live Among Us: Urban Biodiversity

When we think ‘biodiversity’, we generally tend to picture tigers or orangutans. Fortunately for us, biodiversity isn’t limited to big, furry animals.

Biodiversity is “the variability among living organisms from all sources, including terrestrial, marine and other aquatic ecosystems…” 

— The Convention on Biological Diversity (1992)

Urban areas are most often concreted, built and unnatural. However, this shouldn’t deter us from expecting biodiversity to thrive in cities. Living in a developed Malaysian city, I have witnessed frogs, civet cats, bats, tree shrews, snakes, monitor lizards, various species of birds (even raptors!), worms and countless species of insects! And we are yet to include plants in our list of urban biodiversity – fruiting trees, hardwood species, flowering plants, mosses, algae and the list goes on.

A magnificent kingfisher — a rare sight in Malaysian cities but they do turn up occasionally.

It’s easy to think that our built environment belongs only to us humans, while wildlife are meant to be, well, in the wild. Urbanisation often displaces a large majority of wildlife and of those that are fortunate to survive, a small number learn to adapt to our concrete world. In fact, some species thrive so well in urban environments that they have become dependent on us humans for their survival (e.g. pigeons).

So the next time you think ‘biodiversity’, remember the many creatures, big and small, that share your urban home with you.

Connecting With Conservation: Central Forest Spine

A major conservation effort taking place in Malaysia that is hidden in the shadows. The Central Forest Spine Master Plan (CFSMP) birthed in the early 2000s, aims to protect and connect patches of key forest habitats in Peninsular Malaysia through corridors. CFSMP has been in the works since 2014 with a total budget of USD 47 million (RM200 mil). This article covers the basic overview of this project and some of the challenges it’s currently facing.

What is the Central Forest Spine (CFS)?

The Central Forest Spine (CFS) is composed of four major natural forest complexes, that sit in the center of Peninsular Malaysia. The complex covers a whopping 5.5 million square hectares spanning over the states of Kedah, Perak, Kelantan, Terengganu, Pahang, Johor, Negeri Sembilan and Selangor.

  1. Banjaran Titiwangsa (Titiwangsa Range) – Banjaran Bintang (Bintang Range) – Banjaran Nakawan (Nakawan Range)
  2. Taman Negara (National Park) – Banjaran Timur (Timur Range)
  3. Tanah Lembap Tenggara Pahang (Southeastern Pahang Wetlands), Tasik Chini (Lake Chini) and Tasik Bera (Lake Bera)
  4. Taman Negara Endau Rompin (Endau Rompin National Park) – Rizab Hidupan Liar Kluang (Kluang Wildlife Reserve)

Why Is This Plan Important?

The National Physical Plan (NPP) – a national policy for physical land development plans – has identified forest fragmentation as a ‘threat to forest conservation and biodiversity protection’. As opposed to having 4 small, fragmented patches of forest, one large connected forest patch promotes better dispersal of seeds and movement for wildlife, providing better ecological connectivity and improving gene flow.

In other words, one big forest is better than 4 little forests from an ecological perspective. Without movement and connection between patches, species would be limited in their ability to survive and reproduce (e.g. difficulty in finding food, suitable habitats, mates).

Also, as part of efforts to conserve the national emblem of Malaysia, the Malayan tiger – which is found only in Peninsular Malaysia and the southern tip of Thailand (it is no longer found in any other part of Southeast Asia). The Malayan tiger is currently listed as Critically Endangered with only 80 to 120 surviving mature individuals (IUCN, 2018). The CFS provides key habitat area for the Malayan tiger and thus, is critical for tiger conservation.

The CFSMP is one of the two plans the Federal Government of Malaysia has in place for protecting biodiversity and ecosystem services (the long list of benefits humans derive from the environment). The National Tiger Conservation Action Plan (NTCAP) is the other plan in place, aimed at conserving the Malayan tiger.

How Will The Forests Be Connected?

The forest complexes are to be connected by maintaining and expanding forest reserve areas, rehabilitating barren or lost wildlife corridors (pathways that allow plants and wildlife to move between forest patches) and building viaducts for wildlife crossings to link disconnected forest patches.

The movement of wildlife between these corridors would allow for pollination and seed dispersal. The CFS Master Plan report lists some animal groups that would play key roles in these processes:

  • Insects – including bees, butterflies, moths, beetles
  • Birds – including hornbills, sunbirds, flowerpeckers, and spiderhunters
  • Bats – particularly fruit bats
  • Primates – including leaf monkeys, macaques, and gibbons
  • Rodents – including rats, squirrels and flying squirrels, porcupines
  • Sun bears
  • Civets
  • Ungulates – Including most deer species and wild boar

This also means that the protection and conservation of these forests patches provide habitat and conserve the above wildlife as well as countless other species. By protecting our land, we would also stand to benefit more in terms of ecosystem services, tourism, cultural benefits and by means of land management.

“Human activity, particularly the clearing of native vegetation for other non-forest land uses such as agriculture, settlement and infrastructure development, is breaking-up the natural habitat into unconnected parts. Forest fragmentation and edge effects from deforestation have pervasive and deleterious impact on  biodiversity and ecosystem. In particular, habitat fragmentation usually leads to habitat destruction, thus reducing the amount and diversity of plants and animals.” – CFS1 Master Plan for Ecological Linkages (2009)

Who Is Funding This?

The project is being funded by the Global Environment Facility (GEF), an organisation established in the 1992 Rio Earth Summit (a.k.a the game-changing environmental summit). GEF is comprised of 183 countries, international institutions, civil society organizations and the private sector that addresses global environmental issues.

In the last 26 years, GEF has funded over 4500 projects in 170 countries, providing over $17.9 billion in grants and co-financing an additional $93.2 billion for these projects.

What Are The Concerns?

The project is a much needed, and applauded effort in preserving key ecosystems in Peninsular Malaysia. However, this project is one of the first of its kind. A large, landscape-scale conservation effort that is multi-faceted. There is no template or reference point for this project and so it’s a learn-as-you-go type effort as well. Hence, there is a limit on the expertise and skill required to execute such an ambitious task.

Many experts in the field acknowledge that the project cannot achieve its objectives without first resolving certain issues. Due to the project involving a wide range of stakeholders, and discourse in power between state and federal governments, progress has been slower than expected. Other issues such as continued deforestation and illegal wildlife trade that is occurring within these protected areas resonated to the lack of enforcement and corruption that is still haunting the nation, despite the recent shift in ruling government.

Some reckon that a new perspective in viewing the project is needed, possibly a shift in approach and course of action. Strong leadership and better publicity in promoting the project are also some common points that often come up. Ultimately, the project will hugely benefit all of us (directly and indirectly) in the long-run, but while efforts to ensure this project is a success continue, concomittant action to prevent the loss of biodiversity due to the external concerns discussed above are imperative. It’s almost pointless having put together a large, beautiful forest only to have it empty and void of wildlife.

If I Could Save Either Rainforests or Coral Reefs, Which Would I Save?

Firstly, it’s hard to argue which ecosystem is more important that the other. They are both ridiculously gorgeous tropical biomes, which are very structurally complex, highly diverse and therefore, are home to more species than we can count. Both are important to the carbon cycle: producing, storing and processing carbon in it’s various forms for all living things to use and consume (especially as oxygen).

But to answer the question, if I could save either one, I would save the rainforests and here’s why.

Coral reefs support over 500 million people who rely on them for food, jobs and recreation, with an estimated economic impact of $375 billion a year (Kirkpatrick, 2018). Losing coral reefs completely would mean, poverty, hunger and instability as most of our staple seafood rely on coral reefs. The ocean fishing industry which employs 38 million people worldwide would collapse. The human race would take a massive hit without coral reefs, but we would survive. Can’t say the same for marine life though.

Rainforests, on the other hand, are essential for us to live and breathe. Trees provide oxygen and maintain the Earth’s climate, with rainforests providing 20% of the Earth’s oxygen supply. Rainforests house half of the world’s plants and animals, with over 80% of the world’s fruits, vegetables and spices being sourced from rainforests across the globe. That’s a MAJOR source of food for most living beings, especially humans. And we have yet to touch on the cascading effects of removing rainforests on all other ecosystems.

It’s not really a choice anyone would like to make, although losing both these wonderful ecosystems might actually become an unfortunate reality some day, if we don’t protect them.

Differences In Conservation Between Developed And Developing Countries

“How does conservation vary between developed and developing countries?”

“Approach, mentality, response and priority. How conservation is perceived by these two groups, I think varies entirely.”

Generally speaking, developed countries have lost a large proportion of their biodiversity through industrialisation, and therefore place higher priority to preserving what is left. Of course, not everyone living in a developed country values conservation of the natural environment. This increases with education and awareness, although the general response towards conservation is almost always positive. Having ensured the basic needs and rights of its citizens are met, developed nations aim to improve the standard of living. Living in a clean, happy and diverse environment, achieves that goal. Hence, conservation makes sense as a priority.

Developing countries on the other hand, have other economic and sociological concerns that places conservation lower down on their list of ‘Things-To-Do’. Maintaining the diversity of a forest is not a realistic concern when people are struggling to make ends meet. Biodiversity becomes a tool for profit, usually exploited to its maximum potential. This allows the developing country to become developed and prosper, unfortunately at the expense of biodiversity loss. More often than naught, those living in developing countries are also not sufficiently exposed or aware of the importance of protecting our environment.

It’s the classic case of not realising the value of what you have, until it’s gone.

thought-2123970__340

If there’s one thing that both developed and developing countries need, it’s environmental education. People need to know why it’s important to care for our environment. Not just because it’s the morally “right” thing to do but how it directly affects our human well-being. Local conservation efforts need to be publicised, as every individual should be informed of what is happening in our natural environment.

Eliminating ignorance and creating awareness is the first and most basic step in conservation anywhere.

Would The World End Without Insects?

Let’s be honest. Bugs can be gross and annoying. Many of us might have even wondered what the world would be like without some of these pesky critters. The answer might surprise you, but insects play a far more important role in our world than they have ever been given credit for.

Turns out, without insects, all life on Earth would end within 50 years! 

Did you know that there is an estimated 5 to 30 million species of insects in the world? Insects can also be found in every single region of this planet, even in the Arctic (look up the Arctic Wooly Bear Moth)!

It’s a little unfair that as humans, we tend to only associate insects to the pests and parasites that annoy or hurt us. Yes, they carry and spread lethal diseases but for some mad reason, every living being has a role to play in our ecosystem¹.  Even pesky mosquitoes and nasty cockroaches.

insect-3143442_1920

Fact: Spiders are NOT insects. They don’t have an exoskeleton (that’s the hard, outer layer characterizing insects). For more info, visit: Why Spiders Are Not Insects

So why would the world end without insects? What do they really do? 

A lot of insects are herbivores. Herbivores (creatures that eat only veggies), form the base of the food chain, which means they are often food for A LOT of other animals higher up the food chain. Insects that aren’t vegetarian feed on a lot of other different bugs, keeping the food web in check. They also help control insect and plant pests.

The tricky thing about our planet is that everything is linked to something else. You can’t change anything without setting off a chain reaction! Remove insects and you’re taking away food sources for millions of other animals — birds, amphibians, reptiles and mammals. We rely on some of these animals for food and a lot of other services that they provide us. Hey, in some parts of the world, even humans eat insects (great source of protein)!

Insects play a massive role in pollination² and seed dispersal. Over 80% of the world’s plants rely on pollinators to help them reproduce. Insects like bees pollinate a great deal of our food and if they were to go extinct (some bee species are endangered now BTW), a lot of our food crops would die off.  Don’t forget that a lot of our flowering plants are pollinated by insects as well, sometimes by pesky mosquitoes too. Fact: All adult mosquitoes feed on nectar. Females need protein to produce eggs, which they get from animal blood (fascinating, innit!).

Insects don’t just pollinate pretty flowers, they get down and dirty as well. Bugs are big time decomposers, which means they break down dead stuff! From garbage to dead leaves, insects dispose of our natural trash and even convert nutrients back into usable forms, keeping soil fertile. Fact: Museums use carpet beetles, that feed on anything organic — including carpet (hence, the name) to clean skeletons of mammals!

sun-flower-1643794_1920

Did you know we use products made from insects too? Not just honey from bees but wax too! Remember the phrase, “Mind your own beeswax”? Well, beeswax is real! Beeswax is wax produced by bees from a gland on their tummy. It’s used to make candles, lipsticks, cream, lotion and as a base in ointments!

Silk is something else we use a lot of. Silk is made from the cocoons of silkworms. The process is a little cruel as traditionally cocoons are boiled, with the live pupae³ inside, to make silk (I know, horrifying!). However, they’ve since discovered a new method of making silk without killing the pupae (yay!). The medical field uses insects too! Maggots have made a comeback in medicine as they can help remove dead tissue, allowing wounds to heal. They’re also being used to treat ulcers, burns, gangrene and skin cancer. Maggot therapy is real y’all (I’m not signing up for it though).

These are just some of the things we rely on insects for. There’s plenty more they do on a daily basis and definitely some more that we’re not entirely aware of! They keep our planet going, in more than one way. So the next time you decide to squish an insect, just for the fun of it, think twice!

Who run the world? Insects.

¹ Ecosystem is made up of a community of organisms interacting with each other and their environment. Ecosystems can be big or small. This planet is an example of one very big ecosystem.

² Pollination is the process where pollen is transfered to the female reproductive part of the plant from the male part to enable fertilization. Pollination can occur naturally (e.g. wind) but a lot of plants rely on insects (most of the time) and other animals (sometimes) for pollination. 

³ Pupae is the inactive stage of a caterpillar in the cocoon, as it transforms into its adult form (i.e. moth or butterfly).
