Miniature Deer Population Explodes in Singapore After Forest Restoration Success
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Singapore’s greater mouse-deer population has surged fivefold in 15 years due to successful forest restoration efforts and reduced competition after an African swine fever outbreak decimated local wild pigs.
📈 One key stat: The greater mouse-deer population density reached 293 animals per square kilometer by 2024, three times higher than previously recorded anywhere in the species’ range.
💬 One key quote: “I had to perform the analyses multiple times and check my data to be sure there was no mistake,” Marcus Chua, curator of mammals at the Lee Kong Chian Natural History Museum at the National University of Singapore, told Mongabay.
1️⃣ The big picture: The once-extinct greater mouse-deer has made a remarkable comeback on Singapore’s Pulau Ubin island. Scientists discovered a dramatic population explosion of these miniature deer, with numbers increasing fivefold between 2009 and 2024. This surge stemmed from a combination of forest restoration projects that created suitable habitats and a 2023 African swine fever outbreak that eliminated over 98% of the island’s wild pigs. With reduced competition for food and less predation pressure, the rabbit-sized ungulates flourished at unprecedented levels, creating what researchers call an “ecological cascade” effect.
2️⃣ Why is this good news: This remarkable recovery demonstrates the effectiveness of habitat restoration programs, even in previously degraded areas. The reforestation of abandoned quarries, shrimp ponds, and forest enrichment with native tree seedlings created ideal conditions for wildlife to thrive. The greater mouse-deer’s rapid rebound offers hope that other species may also recover in restored habitats. This successful conservation story provides valuable insights for wildlife management across Southeast Asia. The dramatic ecological changes also highlight the importance of long-term monitoring to understand complex ecosystem interactions, especially following disease outbreaks.
3️⃣ What’s next: Researchers plan to continue tracking both mouse-deer and wild pig populations to understand their evolving interactions. They recommend studies on how the high mouse-deer numbers might reshape forest ecology through their herbivory patterns and seed dispersal. Monitoring is especially crucial as wild pigs show signs of breeding again, potentially altering the current ecological balance.
