LISI Update

It is with no small sense of frustration that when LISI’s funding ended earlier this year, we were unable to secure further external funding to maintain Karen’s role as project manager in the long term. Karen has had to leave us for pastures new whilst the wider LISI business group consider our next steps.

Modelling Risk

Recently, GiGL and LISI produced a range of predictive risk model layers for London for various invasive non-native species. Risk modelling is only as good as the data behind it, which is what made this project so innovative. We were able to use local data to create the model on a local scale, down to 100m² …

The Ludwigia Front Line

Of course, having avidly read my previous GiGLer articles, you will know all about the invasive non-native species Ludwigia grandiflora. But what you might not know is that there are other types of Ludwigia growing in London as well. Meet Ludwigia x kentiana, or Kent’s Hampshire-Purslane, a nondescript small hybrid herbaceous aquatic plant currently …

Species alert: Water Primrose

With this year’s growing season starting earlier than normal, we all need to be aware of the possible invasive non-native species that might be popping up in our reserves, parks and open spaces. Over the past couple of years, our attention has turned to a relatively new arrival in Great Britain and in London. Meet water primrose (Ludwigia grandiflora) an aquatic invasive non-native species originally from South America.

Knotweed Undercover

By now, we should all be aware of the potential impacts that Japanese knotweed (Fallopia japonica), an invasive non-native species, can have on local biodiversity, on built structures and on our local amenity. It is important to know how to identify it throughout the year. This task becomes more difficult in winter when it has lost its distinctive leaves and flowers.

LISI Update

LISI is now starting on projects for its upcoming second year. The first of these is the invasive non-native species (INNS) mapping project. This will devise a standardised method for collecting data on invasive species and a way for recorders to get their information into the GiGL database where it can be stored, used and shared.

Fighting the Invasion

Invasive non-native species (INNS) are noted as the second biggest threat to biodiversity worldwide, second only to habitat destruction. They contribute significantly to the threat to biodiversity within the Greater London area. All stakeholders need to work together to ensure effective management.

Australian Invasion

Invasive non-native species are thought to be the biggest threat to biodiversity globally, second only to habitat destruction. They can result in significant declines in native fauna and flora, devastate threatened species and replace rich local biodiversity with a sea of a single species. They are reported to cost the British economy alone around £1.7 billion annually.

Room for improvement

Providing ecological data to private and public sector organisations is one of the core functions of any local records centre. April 2011 saw the launch of GiGL’s new data search service. Our data search system and the content of our reports has been significantly improved in line with GiGL’s aim of enabling evidence-based decision making.…

London Invasive Species Initiative

The London Invasive Species Initiative (LISI) is a newly formed group under the London Biodiversity Partnership, which aims to co-ordinate action to prevent, control and eradicate invasive non-native species in London.

LISI was formed in response to national policy initiatives seeking a co-ordinated national approach …
