In August 2014, CABI released a rust fungus in Berkshire, Cornwall and Middlesex in the United Kingdom as part of field trials into the biological control of Himalayan balsam. ... Dispersal. The research suggests that the best way to control the spread of riparian Himalayan balsam is to decrease eutrophication, thereby permitting the better-adapted local vegetation, that gets outgrown by the balsam on watercourses with high nutrient load, to rebound naturally. Natural Resources Wales has used manual methods, such as pulling plants and using strimmers, to largely eradicate Himalayan Balsam from reaches of the River Ystwyth. Japanese knotweed has risen in prominence recently, you may have even read my 2018 blog post on the subject), it is often maligned by solicitors, surveyors and lenders as public enemy number one, and still regularly sees articles written in the mainstream media eg, The Telegraph (2019), The Independent (2019) and The Express (2019)..

We send "General interest" updates monthly and all other updates from time to time. We recommend that the plants, which are shallow-rooted, should be pulled out and disposed of by composting carefully, or by burning if seeds are present. It grows rapidly and spreads quickly, smothering other vegetation as it goes.

Impatiens glandulifera is a large annual plant native to the Himalayas. woodlands where its spread is aided by prolific seed production coupled with a highly effective dispersal mechanism. 2 Answers. Leaves are stalked, oblong to egg-shaped and have a serrated edge. [7] Presently it can be found almost everywhere across the continent. The fruit wall (seed case, upper left) is made up of five segments. It has now spread across most of the UK, and some local wildlife trusts organise "balsam bashing" events to help control the plant. Our largest annual plant, it flowers from July to October. Plants have a poor root structure so it is relatively easy to remove. [2] Via human introduction it is now present across much of the Northern Hemisphere and is considered an invasive species in many areas. Himalayan Balsam was introduced to the UK in 1839 as a greenhouse and warm garden plant and, within a few years had escaped into the wild. The aggressive seed dispersal, coupled with high nectar production which attracts pollinators, often allows the Himalayan Balsam to outcompete native plants. showering the ground with seeds, like the Himalayan Balsam seed. In 2006, CABI was asked by Defra, the Environment Agency and the Scottish Government to find a natural enemy to help control this destructive weed. [5], The plant was rated in first place for per day nectar production per flower in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative. As a youngster, I would often grow these seeds. Himalayan balsam is an invasive species and was introduced in the mid-19th century as a garden ornamental. By growing to such a height and exploding it can disperse its seeds maybe 3-5 m from the original plant, which can cast into the river and carried on by the flow.

Himalayan balsam is an environmentally damaging weed and its large scale control is virtually impossible. (However, when number of flowers per floral unit, flower abundance, and phenology were taken into account it dropped out of the top 10 for most nectar per unit cover per year, as did all plants that placed in the top ten along with this one for per day nectar production per flower, with the exception of Common Comfrey, Symphytum officinale. However, it is extremely important to exert caution as even the slightest contact with the plant can result in the dispersal of the seeds. After flowering between June and October, the plant forms seed pods 2 to 3 cm (​3⁄4 to ​1 1⁄4 in) long and 8 mm broad (​1⁄4 in), which explode when disturbed,[4] scattering the seeds up to 7 metres (23 feet). All products are produced on-demand and shipped worldwide within 2 - 3 business days. 9.2. Destroying riparian stands of Himalayan balsam can open up the habitat for more aggressive invasive plants such as Japanese knotweed and aid in seed dispersal by dropped seeds sticking to shoes.

As you can see, himalayan balsam can achieve quite a height (3 m) allowing it to disperse its seed by exploding seed pods. Himalayan Balsam was one of my successes. Riparian habitat is suboptimal for I. glandulifera, and spring or autumn flooding destroys seeds and plants.

If all goes well, the project will have it financing its own eradication. Himalayan balsam can reach heights of 3 metres and produce up to 2500 seeds per plant, often forming dense populations along river banks throughout the UK. The cells making up these segments are full of water at a high pressure (turgor-pressure). It is vehemently hated by some and actively persecuted by others. [21][22] It is now widely established in other parts of the world (such as the British Isles and North America), in some cases becoming a weed. Dispersal and Spread: Seeds can be flung up to 7m away from the parent plant with the slightest disturbance. [17] However, a study by Hejda & Pyšek (2006) concluded that, in some circumstances, such efforts may cause more harm than good. It is not native to the UK and the species originates from the Himalayan areas of Pakistan, India and the Kashmir region. [17][18] These plants were all promoted at the time as having the virtues of "herculean proportions" and "splendid invasiveness" which meant that ordinary people could buy them for the cost of a packet of seeds to rival the expensive orchids grown in the greenhouses of the rich. The seeds shed mostly in autumn and are dispersed by the wind and small mammals. Fruit/Seed Description Dispersal Method: The fruit of the Balsam Fir are upright, cylindrical cones.

However, it found its way to waterside situations, such as riverbanks, the banks of streams and, importantly for us, Saintbridge Pond. ", "The biology of invasive alien plants in Canada. It is now widely established in other parts of the world (such as the British Isles and North America), in some cases becoming a weed. Himalayan Balsam also promotes river bank erosion due to the plant dying back over winter, leaving the bank unprotected from flooding.

Himalayan balsam (Impatiens glandulifera) is an exotic-looking annual that has pink, helmet-shaped flowers (also known as "policeman’s helmet”), rapid growth, and an entertaining mode of explosive seed dispersal. [14] Invasive Himalayan balsam can also adversely affect indigenous species by attracting pollinators (e.g. Himalayan balsam is reported to have been first introduced into the British Isles in 1839 (Beerling & Perrins, 1993) as an ornamental species due to its showy flowers and novel explosive seed dispersal mechanism. The common names policeman's helmet, bobby tops, copper tops, and gnome's hatstand all originate from the flowers being decidedly hat-shaped. The pulling technique must be undertaken so that whole plant is uprooted and normally best done if pulled from low down the plant - If snapping occurs at a node the pulling must be completed to include the roots. The aggressive seed dispersal, coupled with high nectar production which attracts pollinators, often allows the Himalayan Balsam to outcompete native plants. [19], Some research also suggests that I. glandulifera may exhibit allelopathy, which means that it excretes toxins that negatively affect neighboring plants, thus increasing its competitive advantage.
