Brian du Preez: Exploring New Plants and Preserving the Fynbos

Hey there! My name is Brian du Preez, and I want to share my passion for discovering new plants and protecting the Fynbos biome with you. Nature is an amazing thing, full of surprises and wonders, and I’m lucky enough to be part of a team of scientists who get to explore and learn new things every day.

Let me tell you a little bit about the Fynbos biome. It’s a unique and diverse ecosystem found right here in South Africa. It’s home to thousands of different plant species, many of which are found nowhere else on Earth. That’s pretty incredible, right?

But here’s the thing – the Fynbos is under threat. Human activities like farming, urbanization, and invasive species are all taking a toll on this delicate environment. If we don’t do something to protect it, we could lose these incredible plants forever.

That’s where my work comes in. My team and I study the Fynbos, exploring its nooks and crannies in search of new and undiscovered plant species. We collect samples, document our findings, and work to understand how these plants fit into the larger ecosystem.

Why is this important, you ask? Well, let me break it down for you. Every plant in the Fynbos has a role to play. They provide food and shelter for animals, they help regulate the water cycle, and they contribute to the overall health and stability of the biome.

By discovering and studying new plants, we gain a better understanding of the Fynbos and how it functions. This knowledge is crucial for developing strategies to protect and preserve this unique environment.

But it’s not just about science and research. We also work closely with local communities and organizations to raise awareness about the importance of the Fynbos and the need to conserve it. We want people to understand that this isn’t just some faraway place – it’s our home, and we all have a responsibility to take care of it.

So, if you’re as fascinated by plants and the natural world as I am, I encourage you to join me in this journey. Together, we can make a difference and ensure that future generations get to experience the beauty and wonder of the Fynbos biome.

I have fond memories of Brian from our time in college. We were both studying ecology at Stellenbosch University, and I remember how amazed I was by his incredible knowledge of the scientific names of all the South African plants. It seemed like he had them all memorized!

But Brian wasn’t just a brainiac. He also had some serious dance skills. He would often bust out his sokkie-sokkie moves, impressing everyone with his nimble feet. It was no surprise when he decided to take his dance talents to the Intervarsity Latin and Ballroom Dance competition.

Since then, Brian has continued to excel in both his academic and dance careers. He’s currently pursuing a PhD at the University of Cape Town, furthering his knowledge and expertise in ecology. And I have no doubt that he’s still tearing up the dance floor whenever he gets the chance.

Hey there! I wanted to share with you an awesome story about Brian du Preez, a PhD candidate at the University of Cape Town. He’s not your ordinary student – he’s become quite well-known for discovering new plant species and finding ones that were thought to be extinct!

Recently, Brian made some incredible discoveries. He found two plants called Polhillia ignota and Aspalathus cordicarpa, which were believed to have vanished a long time ago. The last time anyone had seen them was way back in 1928 and the 1950s! Can you imagine that? But Brian, with his keen eye, managed to find them once again!

But that’s not all! Brian also stumbled upon a completely new plant species! Talk about being in the right place at the right time! This new species of Aspalathus was spotted growing on the sandy riverbanks of the Riet River, which is situated in the Swartuggens Mountains north of Ceres.

I have to say, Brian’s discoveries are truly remarkable. To be able to uncover plants that were thought to be extinct is like finding hidden treasures. And finding an entirely new species? That’s like discovering something that no one else in the world has ever seen before!

This just goes to show that there’s still so much we don’t know about our amazing planet. There are hidden wonders waiting to be found, and thanks to people like Brian du Preez, we can continue to learn and appreciate the incredible biodiversity that surrounds us.

Keep on exploring, and who knows what discoveries you might make!

Recently, I came across the fascinating story of Brian, who made an extraordinary rediscovery of a plant species called Psoralea cataracta, also known as the fountain bush. This plant species was thought to be extinct due to deforestation and agriculture in the Western Cape. It was last seen in 1804 near the ‘Tulbagh waterfall’ and was officially declared extinct in 2008.

However, Brian’s discovery has given us hope. He found a living specimen of P. cataracta, bringing the species back from the brink of extinction. It’s incredible to think that a plant once considered lost can be found again.

Unfortunately, there is a looming threat to these rare and endangered species. Many of the areas where they thrive are at risk of being converted into orchards. This expansion could lead to the ultimate extinction of these plants.

Curiosity got the better of me, and I wanted to learn more about Brian’s efforts to save these unique and threatened plants. So, I reached out to him and asked a few questions about his mission.

So, how did I come across the rediscovery of P. cataracta, the latest sensation in the floral kingdom?

Well, to be honest, I stumbled upon it completely by accident while I was out doing fieldwork for my PhD.

Picture this: I was walking along a dusty jeep track on a private farm, making my way up the mountain. That’s when it happened – right there next to the track, I noticed these little flowers growing so close to the ground. They were tiny, but let me tell you, amidst the scarcity of flowering plants, they really caught my eye.

Now, let’s talk about why I chose to focus my PhD study on the Indigofera genus. What’s the story behind that?

Here’s the thing: Indigofera is a big deal. It’s actually the second largest genus in the legume family within the Greater Cape Floristic Region (GCFR). But, believe it or not, it hasn’t been fully revised yet. Can you imagine?

Hi, I’m Dr. Brian Schrire! I used to work at Royal Botanic KEW gardens, but I recently retired. I’m a global expert on Indigofera, a genus of plants. I spent many years studying the different types of Indigofera found in South Africa, but unfortunately, I retired before I could finish my work.

Even though I’m retired, I’m still here to share my knowledge and provide guidance. It’s a great opportunity to take a closer look at the GCFR (Greater Cape Floristic Region) species and build upon the foundation I’ve established.

Did you know that there are around 30 new species within the Indigofera genus that haven’t been described yet? And that’s just within the GCFR! That’s a lot of exciting discoveries waiting to be made.

So, why is Indigofera so important to me?

The challenge with Indigofera is that there are many species that haven’t been properly identified and described. Without this information, we can’t officially protect them or give them a red list status. It’s crucial for these species to be published in a peer-reviewed scientific journal for their protection.

Have you ever wondered why it’s so important for us to identify and describe new plant species, especially those in the Greater Cape Floristic Region (GCFR)?

Well, let me tell you. There are many species in this region that are unique and at risk of disappearing forever. By identifying and documenting these species, we can better understand and protect them.

You see, the GCFR is a special place. It’s home to a diverse range of plants, many of which can’t be found anywhere else in the world. But unfortunately, the expansion of agriculture is threatening this biodiversity.

When land is cleared for farming or other human activities, plants are often destroyed in the process. And if we don’t even know that these plants exist, how can we work towards protecting them?

That’s why it’s crucial for scientists like myself to study the GCFR and identify new plant species. By doing so, we can raise awareness about these species and their importance. We can advocate for their conservation and work towards implementing measures to protect their habitats.

Maintaining the biodiversity of the GCFR is not just about the plants themselves. It’s also about the animals, insects, and other organisms that rely on these plants for their survival. Losing plant species means losing habitat and food sources for these organisms, which can have a cascading effect on the entire ecosystem.

So, if you’re passionate about protecting our natural world and ensuring the survival of unique plant species, consider supporting the efforts to describe and protect the plants of the GCFR. Together, we can make a difference and preserve the incredible biodiversity of this region for generations to come.

Because of the way humans have impacted natural areas and the spread of invasive alien plants, as well as illegal harvesting for horticulture and medicine, a staggering 2553 plant species in South Africa are now at risk of disappearing forever.

Agriculture plays a huge role in the GCFR, with a wide range of crops grown, including grains, citrus fruits, meat, and even rooibos tea made from the endangered Aspalathus linearis bush. This bush is an example of a plant species driven towards extinction in the wild due to the clearing of natural vegetation for agriculture. Most of the crop farming in the region has taken place in Renosterveld habitat, leading to the loss of over 90% of this type of vegetation. This has resulted in several extinctions and many more species barely hanging on.

So let’s talk about how the forestry industry has affected species loss in the GCFR. I mean, it’s a pretty big deal. Not only have they been planting trees where they shouldn’t, but they’ve also let those trees escape and take over our mountains. Seriously, we’ve got pine, wattle, and Hakea species infesting our beautiful landscapes.

Oh, and let’s not forget about the decline of the Aspalathus cordicarpa. It was thought to be extinct until we found it again in 2016. And guess what? It’s all because of those forestry activities in the Riversdale area. It’s pretty messed up, if you ask me.

But hey, it’s not just the forestry industry. It’s also urban expansion that’s causing a big problem here. Places like Cape Town and Stellenbosch have seen a lot of species go extinct because of all the building and development.

So, what can we do about it? Well, we need to start getting rid of these invasive species. And we need to do it fast. There are areas, like Tokai Park, that we can rehabilitate to bring back some critically endangered vegetation. It’s our best shot at saving what’s left. And trust me, we need to save it.

I want to emphasize the importance of not destroying any more untouched land. We need to be mindful of where we choose to develop for cities or agriculture in the future. It should only be done on land that has already been disturbed or destroyed.

There’s been a lot of talk about how changing our diet can help reduce our impact on the planet. But will it really make a difference in preventing these quiet extinctions?

Changing our diet alone is unlikely to solve the problem. Most of the land suitable for agriculture has already been used. To prevent further loss of natural habitats, we need to find ways to increase crop yields on existing farmland or slow down population growth. Otherwise, we’ll continue to transform untouched habitats for urban or agricultural purposes.

What can we do to help protect plant species?

I’ve been thinking a lot about how we can make a difference in conserving plant species. It’s interesting that every little action we take can have a big impact on the health and diversity of our plant life. So, what else can us ‘average-Joes’ do to contribute towards this important cause? Let’s explore some ideas together.

1. Support local organizations and initiatives. You can start by finding out if there are any local groups or projects dedicated to plant conservation in your community. Maybe there’s a botanical garden, an arboretum, or a nature reserve nearby that could use your support. You can volunteer your time, donate money or resources, or even participate in educational programs they offer.

2. Plant native species in your garden. Native plants are specially adapted to the local ecosystem, so they require less water, fertilizer, and pesticide. By choosing native plants for your garden, you can create a habitat for local pollinators and other wildlife. Plus, they can add beauty and character to your outdoor space.

3. Reduce your water consumption. It’s easy to forget that water is a precious resource, but conserving it is crucial for the well-being of plants. You can make a difference by fixing leaks, watering your plants in the early morning or late evening, and using a rain barrel to collect water for your garden. And don’t forget to be mindful of your daily water usage indoors as well.

4. Say no to invasive species. Invasive plants can threaten the survival of native plant species by outcompeting them for resources. When you’re landscaping or gardening, make sure to choose plants that aren’t considered invasive in your area. And if you find any invasive plants growing in your yard or neighborhood, take action to remove them and prevent their spread.

5. Educate yourself and others. Knowledge is power, and by learning more about plant species, their importance, and the threats they face, you can become a better advocate for their conservation. You can read books, watch documentaries, join online forums, or even attend local workshops and seminars. Share what you learn with others, and together we can raise awareness and inspire action.

Remember, every effort counts when it comes to protecting plant species. By taking these simple steps in our everyday lives, we can make a positive impact and help preserve the beauty and diversity of our natural world. So let’s roll up our sleeves and get to work!

Pine plantations like Tokai are not environmentally friendly at all. They use an astonishing 40-50 liters of water per tree every single day. On top of that, they pose a serious fire risk and harm the biodiversity of the region.

I know you might be wondering how you can help save our threatened species. It’s not easy because we can’t always be directly involved in their conservation. However, there are steps you can take as an individual to make a difference. The first thing is to be aware of the dangers that our native plants face and the importance of living sustainably for the sake of our planet.

Here are a couple of actions you can take:

1. Do not support any developments in areas that are ecologically sensitive or where natural vegetation will be destroyed.

2. Join organizations and campaigns that advocate for the protection of natural areas. Also, speak out against those who want to harm our natural environment.

If you’re looking to make a difference and get a little dirty, why not join your local “Friends Of…” group? These groups often organize activities, like removing invasive alien trees, that help preserve our natural environment.

It’s important to be mindful of the information we consume, especially in the media. There are instances where fake news spreads about the supposed benefits of alien trees. However, we must question whether it’s worth keeping these trees in our landscapes, when we have the opportunity to protect and restore our precious undeveloped land.

Recently, someone made a valid point: you can’t truly conserve something unless you love and appreciate it. In your opinion, what are the best places to visit in the Western Cape that showcase and celebrate the province’s incredible floral diversity?

Wow, have you ever seen wild flowers just take over a place? It’s like nature’s own special brand of magic. I’m talking about those unbounded, untamed flowers that spill into towns, dance along highways, and transform fields into a riot of colors.

Now, there are so many incredible places to explore, and it all depends on what you’re looking to see. If you’re a succulent plants and daisies fan, then Namaqualand is the place to be! August and September are the prime months when this mesmerizing destination comes alive with vibrant blooms. Trust me, it’s a sight you won’t want to miss.

For all you fynbos enthusiasts, Table Mountain and Cape Point are the go-to spots. They offer breathtaking views, stunning landscapes, and an abundance of fynbos, which is a unique type of vegetation found only in the Western Cape. And while you’re at it, don’t forget to check out our incredible botanical gardens. They’re like secret oases tucked away, showcasing a mind-boggling variety of indigenous plants.

When it comes to exploring mountains, it’s important to think outside the box and discover hidden treasures. Instead of going for the well-known and risky climbs, why not venture into lesser-known areas? That’s where you’ll find real gems, like the Overberg Renosterveld Reserve.

This reserve is tucked away amidst vast fields of wheat and canola. It may not be the most isolated or dangerous, but believe me, it’s worth a visit. In fact, it’s home to several plant species that have only recently been discovered, as well as some truly stunning flowers.

Did you know that fire can actually benefit biodiversity in the fynbos biome? That’s right, contrary to popular belief, fire is an important ecological process in this region. In fact, the first few years after a fire are when you can witness the most spectacular displays of flowers.

Imagine a dazzling array of orchids, gladiolus, and moraea species, all blooming in the first spring and summer after a fire. It’s a sight to behold! And it doesn’t stop there. In the following years, you’ll be treated to an abundance of vibrant legumes, daisies, and restios.

If you’re a fan of the stunning Proteaceae flowers, I recommend visiting mature fynbos. However, if you want to experience the very best that fynbos has to offer, keep an eye on the mountains that have recently burned. That’s where you’ll find the most extraordinary and diverse flora.

So, what species should you be on the lookout for during your travels? And are there any tools that can enhance your experience?

Hey there! So here’s the deal: species diversity in this region can be pretty different from one place to another. You gotta keep your eyes peeled for any flowers, big or small, when you’re out and about. Some of ’em might not look like much from far away, but trust me, they’ll surprise you up close!

Oh, and don’t forget your camera or phone! Snap away at all the plants you come across. There are tons of books and PDFs out there that can help you learn about the local flora. Just find one that covers your area, flip through it, and start soaking up plant knowledge a little bit at a time.

If reading ain’t your thing, don’t worry! You can also take pictures of plants in the field and upload them to a cool website called iNaturalist. They even have a free app for Android and Apple. The best part is that experts can check out your pics and tell you what plants you’ve found. Plus, you can chat with them and learn even more!

When is the perfect time to embark on a flower-spotting adventure?

Wondering when you should plan your flower-spotting excursion? Late winter to early summer is your answer! During this period, the Greater Cape Floristic Region (GCFR) comes alive with beautiful blooms. But let me tell you a secret – there’s something blossoming in the field all year round! March and April are particularly special as you’ll get to witness the spectacular Amaryllid lilies in full bloom. So, make sure you mark these months in your calendar for an unforgettable floral experience.

Allow me to introduce you to a unique experience – sokkie amongst the flowers!

Hey, have you ever thought about doing something beyond your PhD?

Got any plans after your PhD?

I don’t have any specific plans yet, but I’m really interested in continuing my work on the classification of GCFR legumes in some way. And of course, I want to spend as much time as possible doing fieldwork. Right now, my main focus is on producing a solid PhD and doing a thorough revision of Indigofera for the GCFR. If everything goes well, we’re even thinking about publishing a book about the Indigofera plants in the GCFR after I finish my PhD.
