Gorse (Ulex europaeus; Fabaceae)

Gorse is the worst pest in New Zealand. It has been a serious weed in New Zealand for over 100 years and continues to invade pastoral land, forest plantations, and vulnerable natural habitats.


Gorse first arrived in New Zealand in the early 1800s. Seed was brought in by English settlers to grow plants for hedging. A lack of natural control agents in New Zealand in combination with high seed production, unpalatability to stock, and invasive, colonising growth habitats have allowed gorse to become the widespread problems they are today.

Research into the biocontrol of gorse began in the 1920s, and the decision to mount a full-scale biological control programme against gorse in New Zealand was made in 1988 after a full "Environmental Impact Assessment" was written to support the biocontrol of gorse programme.

Gorse is a perennial, evergreen shrub ranging from 3 feet to over 10 feet tall. Seedlings are compact, with trifoliate leaves and thin expanded leaflets typical of legumes. With plant maturity, the leaves develop an awl-shape (spinelike). Well-developed branch spines also grow in the leaf axils. Overall, gorse plants are shrubby with stout and erect spreading branches with angular stems and a terminal thorn. Branches mature from green to brown.

The plant habit is dense, sometimes 30 feet in diameter with a centre of dead foliage. The shiny yellow, pea-like flowers are ½ to ¾ inch long, with an ovate banner (upper petal), oblong wings (lateral petals) and keel (lower, united petals). The wings are larger than the keel. The calyx is pubescent and deeply two-lipped. The upper lip is 2-toothed and the lower lip is 3-toothed. The ten stamens are monadelphous. The flowers are solitary, and clustered at branch tips. The seedpods are hairy, ½ to ¾ inch long, and brown when ripe. The pods burst and scatter seeds for several feet. The seeds are smooth and shiny, olive to brownish. The root system consists of a taproot, lateral roots and adventitious roots.

This plant here is growing along the cliff between Murrays Bay and Mairangi Bay in amongst the native plants that grow there. If it isn’t cut out it will soon start taking over the native bush. As you can see the flowers will be turning into seeds soon and will spread everywhere.

I realise it should be sharper but as the plant was hanging out over the cliff this was as far as I could reach it. The blue in the background is the sea between the two beaches.

Hello Janice,

The note is really interesting. When my gf and I visited NZ we like the Gorse a lot as it is so yellow and so cheerful. soon after we learned that it was the biggest pest in NZ and it suffocates a lot of endemic plantlife. Thanks for the picture and the note. Well done & TFS!

Regards,
Pieter

Excellent colors, very nice contrast.

This looks like a painting - and that's great.

Nice shot Janice,
Excellent colours, crystal clear detail, good sharpness. Great composition and nicely exposed.
Thanks for posting, have a good week.

Those bloody English! I'm rather fond of gorse, great stuff for finding bugs and spiders in. The note is great and a good picture that is very familiar to me!

Hard to believe that this great looking plant could be a pest. Beautifull picture, sea in BG added great mood to it. Nice yellow flowers and last but not least very interesting note. Good work Janice!

A nice shot Janice,
It looks sharp enough to me and be careful on those cliff edges! :))
Great colours and detail,the blue of the sea gives a perfect background.
Great work,well done.

Hi Janice,
beautiful plants from the New Zealand. Nice, delicate flowers. Good sharpness and colours. I like it.
Regards,
Aleksander

How unfortunate that something so lovely should be considered a pest, Janice.
It is a well captured pest at that, considering the position of this particular shrub. Well done, thank you.

We have it in the UK, especially in the New Forest, but the ponies keep it downa fair bit!.....It really hurts though when you go running thru it in pursuit of a butterfly...LOL..

Nice work Janice! Great lookin' weed although I wouldn't want to lose my balance near one! ;-) Well done on the composition and details and an excellent note!

Janice, we have a simular plant ,Scotchbroom, also considered a pest now, although according to this article it was planted on highway banks to prevent erosion years ago, and has since taken over. If you start leaning over cliffs for photos, I'm going to have to start calling you "Julie" as that's what she does also. It was worth it as this shot shows off the yellow blooms nicely. I love the bluish background also, well done.

Hi Janice,
Another plant that has drawn my blood on occasions.

I feel your image is a little dark and you appear to have save it as a jpg with two much compression as I can see some jpg artefacts.

Hi Janice
Pests are simply organisms that have a robust constitution. If it were difficult to grow (and hence rare), we would be trying to find ways of cultivating it.
In the US at this latitude, we have a similar problem with a type of European Honeysuckle. It has taken over the understory in many areas and I must continue to fight its woodiness in the yard. Farther south, kudzu from the Orient is an invasive exotic.

I dislike this ghastly plant intensly.It has caused me much pain on numerous occasions.Do you think the soft focus bits could have been moving in the wind?
You should have said "NZs worst PLANT pest"
I think as a pest,the Possum is a fair contender for the worst,along with the rat,which is decimating many of our native bird species by eating their eggs etc.
B******s!

Hi Janice,
A very interesting story on the Gorse. I hope your country is making some headway trying to control that nasty invasive plant.

Considering you were hanging over a ledge to take the photo, I think you did a great job. Nice detail, colour and exposure. Janice/Canada

A great shot of a great pest! Just don't let them introduce another pest to control this one - the cure always seems worse than the disease!
