Change to pricing of ARMI participant packs to take effect from Wednesday 1st April 2020

Change to pricing of ARMI participant packs

Please be advised that the cost of ARMI participant packs is increasing from 1st April 2020. This is not a decision that we have taken lightly but it is necessary in order to cover production, order fulfilment, and invoicing costs following more than six years of ARMI participant pack pricing being frozen. During that time, production costs have increased, funding pressures have increased, and costs to the Riverfly Partnership in general have increased. We held off from increasing ARMI participant pack prices for as long as possible but it is no longer sustainable to provide them at a subsidised price.

Please continue to order packs by email from Kirsty Hadwin at FBA, Windermere (KHadwin@fba.org.uk). Kirsty will fulfil your order and issue invoices accordingly.

The cost to purchase packs from 1st April 2020 will be as follows:

ARMI participant pack option 1 - cost £10 per pack plus p&p

This is the most commonly requested option. Folders, 'Riverfly monitoring' guides, Dynamic Risk Assessment cards, RP contact cards, Lyme/Weils cards, sharps injury cards, RP cards, and numbered certificates will be sent by post (certificates should be posted directly to the relevant RP certificated tutor). The remaining inserts will be sent electronically via email to the local host to be printed and collated into packs with the posted materials.  

ARMI participant pack option 2 - cost £20 per pack plus p&p

This option is available if the capacity to print off materials locally does not exist. All materials are collated into individual packs and placed in folders prior to posting. Certificates should still be posted directly to the relevant RP certificated tutor.

Thank you from all at the Riverfly Partnership for your support and understanding

Changes on Our Website

You may have noticed our fresh new look. As well as updating our style we have trimmed down content, made our pages mobile-responsive, added new features to the databse, and dotted help text around the site.

You will find the most changes in our Data tab at the top of the page, where there are now lots of options to view and download the data.

We've also added a Forum. We hope this will become a community space for discussion on all things riverflies, including fish, monitoring, identification, river health and conservation.

If you get stuck you can refer to our new User Guide also available in the Resources section.

We are still making a few background changes. If you spot anything amiss, or have any suggestions please screenshot it if possible and send the details to us at Ben@riverflies.org or Alex@riverflies.org

From all the team at Riverfly and the FBA thank you so much for your patience and support. We hope you enjoy the new website.


EA Challenges and Choices consultation

The Environment Agency is seeking your views on the challenges our waters face and the choices and changes we all need to make to help tackle them.

By responding to the consultation you will be helping to shape the management of the water environment. The information gathered through this consultation will help the EA update the current river basin management plans, starting with the publication of draft plans in 2020.

They will also use your responses to help consider how some of the current approaches to the management of water in England will need to change in response to a changing climate and a growing population. The EA are calling this work the Water Story.

Covid-19 Update

Now that government has further restricted travel outside of the home so that it only permitted if for any of the four essential reasons, it is clear that ARMI and Riverfly Plus activity, including monitoring, should cease until further notice. 

Riverfly activity cannot be considered essential work and associated travel is certainly non essential. In addition, we have to consider those identified as vulnerable within our society, and which may either be Riverfly volunteers themselves or, if not, living or working with vulnerable people.

Ongoing advice

We recommend that everyone regularly checks the latest government and NHS advice by visiting www.gov.uk and www.nhs.uk. Always bear in mind that the situation regarding coronavirus is constantly and rapidly changing.
