Tips on how to remove 3 new invasive plant species

It’s quite simply not that easy to remove any invasive alien plant. Each species requires a different technique to try to prevent it from re-growing.

The same applies to three ‘new’ and emerging invasive alien plant species found to be growing on the Agulhas Plain: Kangaroo Paw, Mauritian Hemp and Australian bottlebrush.

The species are now being cut down and removed by a Flower Valley alien clearing team, partnering with the South African National Biodiversity Institute (SANBI).

Here are practical tips to – as successfully as possible – remove these plants, and prevent them from spreading.

1. KANGAROO PAW (Anigozanthos flavidus)

If the Kangaroo Paw plants are in dense stands, SANBI advises the careful use of herbicide (but extreme care must be taken to prevent spray drift, which could affect other species). Where plants are pulled out, the biomass must be placed on large black plastic sheets, and then they must be sprayed again with herbicide, to enhance decay.

2: MAURITIAN HEMP (Furcraea foetida)

The leaves of the Mauritian Hemp must be slashed, before it is foliar-sprayed. Without this step, the plant may not take in the herbicide. Again, care must be taken to prevent spray-drift when applying the herbicide.

3: AUSTRALIAN BOTTLEBRUSH (Melaleuca linearis)

Small plants should be hand pulled – although you must ensure that the roots are removed. Where the trees are cut down, herbicide must be applied to the stump immediately after cutting down the plant. SANBI recommends using a diluted imazapyr herbicide.

In the case of the Australian Bottlebrush, there is also extreme concern regarding the seeds. Each capsule on the seed cone contains around 60 seeds – which like Hakea, opens a few days after being killed. This facilitates the spread of the species.

In the Stanford area, where the Bottlebrush has been found, the fantastic, supportive landowner is ensuring that ALL seeds are removed from all the cut trees. This is not easy work, but is vital to prevent spread.

Look out for these 3 ‘new’ threatening invasive plants

Three new and emerging invasive alien species are being targeted on the Agulhas Plain.

The plan is to rid the area of these three species – before they spread beyond their current farm boundaries, threatening our region’s biodiversity. 

A Flower Valley Conservation Trust alien clearing team has worked to remove the species, partnering with the South African National Biodiversity Institute (SANBI).

And even though the SANBI-funded project ended in March 2019, residents of the Agulhas Plain are still asked to get involved: To contact Flower Valley Conservation Trust if you come across any of these three species.

(This way we can ensure they’re removed in the next funding cycle). 

 

The three are:

  • Kangaroo Paw (Anigozanthos flavidus)
  • Mauritian Hemp (Furcraea foetida)
  • Australian Bottlebrush (Melaleuca linearis)

 

 

Here’s why the experts are so concerned about these invasive species:

1. KANGAROO PAW

This species is native to Western Australia. But it’s very adaptable to most soil types – even water-stressed areas (like South Africa). It’s immune to most fungal attacks – and SANBI warns it could pose a threat to the rich biodiversity of the Agulhas Plain. It has been growing on two farms in the Plain, where our alien clearing team has been working to remove them.

2: MAURITIAN HEMP

This species is originally from the Caribbean and tropical South America. But it’s extremely invasive, and not only in South Africa (it’s invasive in Eastern and South-Western Australia too). You’ll find it in the Western Cape, Eastern Cape, Mpumalanga and KwaZulu-Natal. It was found to be growing in the Nuwejaars Wetland Special Management Area – with immediate action taken to remove it. It’s listed as a Category 1a plant invader – which means it must be eradicated.

3: AUSTRALIAN BOTTLEBRUSH

The narrow-leaved bottlebrush is very concerning to SANBI because it so easily outcompetes native vegetation. That’s a worry for our rich fynbos landscapes. It has been found on a farm near Stanford in the Plain (although it has also been found in Wolseley, Tulbagh and Rooi Els). It’s a member of the Myrtle family, endemic to New South Wales and Queensland in Australia.

While this project may have completed, we are still keeping an eye out for emerging invasive species, and by working with partners, are looking to remove them before they become a problem. 

If you see these 3 invaders (or another you’re concerned about), contact Stanley Engel. Email: stanley@flowervalley.co.za (preferably include your photos of the plant). 

An unusual day in the life of a Field Monitor

Flower Valley’s field monitors

Climbing a fynbos mountain daily, seeing wildlife up close and personal? That’s exactly what fynbos harvesting teams do every day while picking stems for the market. And Flower Valley’s field monitors got to experience just what that entails for a number of months.

The Sustainable Harvesting Programme team has undertaken intensive field monitoring across the Agulhas Plain, looking at the impacts of fynbos harvesting and establishing practical methods to measure this impact over time.

So Flower Valley’s two monitors, Daylene van Riet and Berna Jacobs, followed harvesting teams and climbed mountains to evaluate the impact of fynbos harvesting.

Just like harvesting itself, being a Fynbos Field Monitor is an unusual job that usually includes a truly South African adventure while still getting the job done. And it’s not for the faint-hearted.  

For example, the monitors had many encounters with wildlife while moving through the fynbos, including snakes that only give you a moment’s notice of their presence. Daylene nearly stepped on a Puff Adder (the Puff Adder is one of the deadliest snakes in Africa) – but luckily the snake slithered away quickly to protect itself. And Berna had a close encounter with a Rinkhals Cobra (a Spitting Cobra), which also fortunately slithered away into a bush with no harm done.

Daylene and Berna also had an encounter with a massive male baboon. The baboon’s warning call from less than one 1 meter away in a Protea bush sent all three, including the big baboon, running into different directions.

The presence of baboons also played out in other forms. After surveying a property, the team noticed that fynbos stems – particularly Protea repens – were being broken off. This was certainly not being done as per the Sustainable Harvesting Code of Best Practice. Only after an investigation did they discover that this was not the work of a harvesting team – but rather baboons breaking the Protea flower heads to drink the nectar.

Here’s the lesson we learned: One may not realise the dangers and risky adventures that harvesters experience daily while collecting beautiful flowers for bouquets.

Thanks to our fierce Field Monitors, Berna and Daylene, for the vital information they collected, and for reminding us of the extraordinary job that fynbos harvesters do.

 

Fynbos foodie options and their medicinal benefits

Fynbos offers a number of tasty foodie options. So on World Food Day (16 October), we’re taking a slightly different view of fynbos – to see how to use fynbos in food (responsibly, of course), and some of the medicinal benefits.

Great SA Bake Off Judge, Tjaart Walraven, and Vineyard Chef, Carl van Rooyen, compiled a fynbos-infused selection of sweets and savoury treats.

So here are some of the menu options presented earlier this year at a Fynbos Fusion event (hosted by Flower Valley Conservation Trust, Pick n Pay and the Vineyard Hotel).

 

1. Wild Rosemary-infused Chicken Mayonnaise Filled Ciabatta

Wild rosemary offers a natural way to fight an oncoming cold. It also promotes healthy hair and skin, with rich anti-ageing properties.

It also helps ease off a migraine, and reduces stress and anxiety.

 

2. Orange and Citrus Buchu Crème Brûlée

Buchu offers wonderful medicinal benefits. For example, eating buchu or drinking buchu tea helps to improve your immune system (a great natural way to re-energise when you’re feeling a bit flat).

It’s also handy if you have a bit of a hangover, or a bladder infection. And it serves as a natural insect repellant against mosquitos.

 

3. Sour Fig Jam Baked Cheesecake

Sour figs are considered to be anti-fungal, antiseptic and antibacterial. They’re also great for treating scars: they’re said to help regenerate cells, while the juice helps to treat burns and wounds.

Sour figs also help when you have digestive troubles, and mouth and stomach ulcers.

Of course, we recommend you harvest your fynbos responsibly – not damaging the plant during the picking process, and leaving seed stock in the veld, so that new plants can continue to grow across the landscapes.

Meet Daylene, our SHP field monitor

The Sustainable Harvesting team has received additional support to test new fynbos monitoring methods. A field monitor, Daylene van Riet has joined the team. She will now work with fynbos harvesters who are members of the Sustainable Harvesting Programme, together testing the field monitoring method and capturing fynbos harvesting data.

Daylene will also assist veld harvesters to follow the sustainable harvesting principles, record field assessment data correctly and complete independent fynbos assessments and capture this information digitally.

 

Rupert Koopman, Botanist for CapeNature and member of the Sustainable Harvesting Steering Committee joined the SHP team with Daylene, to advise on the monitoring system and improve it where necessary. Trevor Adams, Botanist for SANParks, also joined the team recently to better understand the monitoring methodology. Adams specialises in monitoring species of special concern in fynbos and wetlands.

With this monitoring system in place, the Sustainable Harvesting team will remain on top of harvesting trends, to help support the responsible harvesting of key species. The system is being rolled out in the Agulhas Plain area as a starting point, and will later be implemented across other harvesting areas across the Cape Floral Kingdom.

Silver brunia

Silver brunia is helping to focus attention on the Cape Floral Kingdom – and specifically, the need to harvest fynbos sustainably.

In an article featured in the Business Day, the demand for fynbos is highlighted – with fynbos exported to Europe, Asia, Russia and many other global markets. That also shows the importance of sustainably managing the fynbos industry, and supporting research and monitoring to better understand the effects of harvesting fynbos species.

Flower Valley’s Sustainable Harvesting Programme was launched to support responsible action in the fynbos sector. Supported by the WWF-SA Nedbank Green Trust and the European Union, Flower Valley has been working with landowners and harvesters across an area of 75,000 hectares in the Cape Floral Kingdom, encouraging environmental best practice, and social and labour compliance.

Making fynbos monitoring ‘easy’

fynbos monitoring

Fynbos monitoring

There’s nothing simple about monitoring fynbos populations – like seeing how fynbos harvesting may affect fynbos in an area over time. So the Flower Valley team has teamed up with scientists and students to find ways to more easily see how fynbos changes in the long term.

Fynbos harvesters and teams head out into the veld daily, picking fynbos species that are used in bouquets, and ultimately sold around the world.

While tons of fynbos is exported out of the country every year, scientists have only been able to use expensive and time-consuming methods to see how this impacts on the landscape itself.

 

Using what we have

Now the Flower Valley Sustainable Harvesting Programme (SHP) team is working with experts, to better use some of the tools we already have.

As a member of the programme, a landowner or harvester is shown how to complete a field assessment on the land. This assessment looks at how well harvesters are complying to environmental standards (as captured in our SHP Code of Best Practice).

Now this field assessment has been reworked to include a monitoring aspect, like including estimates of how abundantly a fynbos species may occur in an area.

 

Support from Stellenbosch University

The SHP team received help from Conservation Ecology students from Stellenbosch University, under the leadership of Flower Valley Trustee, Rhoda Malgas.

The students helped to test the field methods used in the assessment, to see how practical and easy they were to use.

According to Kirsten Retief, the Conservation Extension and Applied Research Coordinator at Flower Valley, the work so far will make it easier for landowners and harvesters to see changes in their veld over time.

 

Combining science and practicality

“The methods we develop have got to be easy for anyone to use. But they must still have scientific integrity. The data we collect from these field assessments will be used to spot fynbos trends over time. And to react quickly if the assessments point to any areas of concern,” she said.

The Sustainable Harvesting Programme is Flower Valley’s flagship programme. The programme gives support to landowners and harvesters to meet best practice environmental standards, as well as social and labour standards. The aim is to help the niche fynbos industry become even more attractive as an ethical industry – while ensuring fynbos landscapes are protected.

The programme is funded by the WWF Nedbank Green Trust and the European Union.

Answering tough fynbos questions

fynbos questions

Lea Cohen

Flower Valley is introducing new skills and capacity to answer difficult questions around fynbos use. With the help of a database expert, the team is now able to use internet-based databases, to help analyse trends in fynbos.

We’ve worked with fantastic volunteers, such as Lea Cohen, who shared her knowledge and expertise on open source database management systems with the Sustainable Harvesting Programme.

 

Experience on 3 continents

Lea has varied experience working and volunteering for a number of conservation NGOs on three continents: North America, South America and Africa. Her impressive tertiary background includes Geography, completed at UCLA, and an MSc in Conservation Biology completed at UCT. She has since specialized in GIS and data management systems.

She introduced the Sustainable Harvesting team to programmes used by international companies to manage large datasets and geospatial information.

This will allow the Sustainable Harvesting team to use information we’re collecting to answer more complex questions concerning fynbos use across the Cape Floristic Region. Watch this space!

Your own Erica ID kit:

There are around 660 Erica species in the Cape Floral Kingdom. On Flower Valley Farm, we’ve got 19 Erica species. (Most notably, you’ll find the Endangered Erica irregularis.) We’ve compiled an Erica ID kit of the main Erica species you’ll find in our area. And we’re making this kit available to those who have Adopted a Hectare on Flower Valley Farm.
