Poole Harbour Surveys

The surveying and monitoring of birds and their habitats is vital for their ongoing protection and conservation. Numerous surveys have been and continue to be carried out right across the harbour, creating a unique picture as to what is happening within this nationally and internationally important site.

This section of the website will allow you to peruse through various reports, new and old, giving you a detailed insight into specific species and habitats.

All surveys published on these pages have been done so with the permission of the surveyor’s themselves or the owners of the surveys.

Moths of Poole Harbour - Phase 1 report

Knowing how other parts of the harbours eco-systems are functioning is vital, plus it gives a good indication as to how bird populations may be affected in the long and short term. In the summer of 2017, Birds of Poole Harbour commissioned a two year ‘Moths of Poole Harbour’ study with the aim to gain knowledge of moth species occurring around the harbour their distribution, abundance and to some extent, their habitat requirements. Starting in July 2017, Phase 1 of the study was extremely successful with numerous public engagement events taking place with one or two 'goodies' caught along the way. The full report for Phase 1 can be read below.

Breeding gulls of Poole Harbour 2016 - Nick Hopper

In 2016 ‘Birds of Poole Harbour’ commissioned Nick Hopper to carry out a full census of breeding gulls within our Poole Harbour boundary. The survey was carried out during the spring and summer of 2016 and the findings as well as the results took us a bit by surprise. No doubt, many of you would have read about the illegal egg harvesting of Black-headed Gull and Mediterranean Gull eggs that was uncovered through carrying out this survey, and finally, before you read the report why not have a guess at how many Herring Gull and Lesser Black-backed Gull breed within the Poole Harbour area.....you may be surprised!

Middlebere sightings August 2014 - June 2016 by Simon Kidner

The Avocet Hide at Middlebere is one of the best places to watch birds in Poole harbour, especially in the winter when birds of prey and wading species frequent the upper end of the channel on a rising tide. The 'public diary' in the hide provides a great account of what can be seen at Middlebere right the way through the year, however without visiting the hide, you won’t get to read the full accounts of the publics sightings. However, local Middlebere regular Simon Kidner has kindly written up a full account of all sightings from the ‘public diary’ ranging from August 2014 to June 2016. This report will provide you with a good understanding of the the best times to visit Middlebere and what you can expect to see.

Many thanks to Simon for providing us with this report and he has even provided a breakdown at the end of the report of dates of some of the hides most welcomed visitors.

Numbers And Distribution Of Black-necked Grebe And Other Waterbirds at Studland, Dorset 2005/06

During the 1990’s Poole Harbour and Studland Bay were listed either separately or together as being of national importance for wintering Slavonian Grebe and Black-necked Grebe. Due to lack of coordinated counts over a period of time, repeated counts were made from the Studland Shorline especially for this report to redress the lack of monitoring. This PDF was donated to The Birds of Poole Harbour charity by The Poole Harbour Study Group to be used as a reference document on our surveys page

Important Birds Of Poole Harbour 2002

Poole Harbour and its environs, has long been recognised nationally as being of high biological importance. In 1964 the harbour was designated under The National Parks and countryside Act 1949, section 23, as a Site of Special Scientific Interest (SSSI). Within the harbour area, the variety of different habitats contributes significantly to its biodiversity and to its support of nationally and internationally important bird populations.This PDF was donated to The Birds of Poole Harbour charity by The Poole Harbour Study Group to be used as a reference document on our surveys page

Poole Harbour Breeding Redshank Survey 2014

The British breeding population of Redshank is internationally important. After surveys were carried out in 1997 and 2004 to assess the number of pairs breeding on saltmarsh within Poole Harbour, the RSPB decided to carry a repeat survey in 2014 to see how the population had changed.

POOLE HARBOUR WeBS COUNT DATA 2009 - 2014

WeBS stands for Wetland Bird Surveys and is a national survey set up and organised by the British Trust for Ornithology (BTO). Each winter over 30 volunteers go out on specific dates, at specific times to try and count every wetland bird species within Poole Harbour. The surveys begin in September of each year and finish the following March and are carried out to assess the numbers of each species visiting Poole Harbour each winter. Poole Harbour is nationally and internationally important for a number of species so WeBS counts are an essential part of monitoring these over-wintering populations.

The attached document highlights peak counts of each wetland bird species during the 2009/10, 2010/11, 2011/12, 2012/13 and 2013/14 winter periods.

Starlings of Poole Harbour - A winter roost report

Each winter many thousands of Starling enter the UK from mainland Europe often forming large evening murmurations in rural, urban and semi-urban areas. Roost sizes can vary greatly year on year, and in this report Nick Hopper focuses on the winter roost behavior during the 2014/15 winter period within Poole Harbour.

Corvids of Poole Harbour

From September 2007 to March 2008, Nick Hopper was commissioned to carry out a study on the roosting, feeding and breeding habits of all Corvid species within the Poole Harbour area. During the 2014/15 winter period Nick re-surveyed Magpie roosts as part of our Birds of Poole Harbour winter roost study. He has combined both studies into one full report, which you can now read here.

Pied Wagtails of Poole Harbour - A winter roost survey 2014/15

Every winter in Poole Harbour, winter-roosts of many different bird species are formed in a selection of habitats. Some, like the Grebe roosts are well studied and documented, but others are still a total unknown. During the winter period of 2014/15 Nick Hopper was commisioned to carry out a survey into the winter roosting habits of Pied Wagtail, Starling and Magpie. In the first part of his three part survey you can read about the behaviour and location choices that Pied Wagtails adopt pre and post roost during the cold winter months.

Population and distribution of wintering Woodcock in Poole Harbour - Nick Hopper

In Autumn 2013, ‘Birds of Poole Harbour’ commissioned environmental surveyor Nick Hopper to monitor the number of over wintering Woodcock within the Poole Harbour area. Due to their shy nature and nocturnal feeding habits, gaging a true over-wintering population of Woodcock has always been difficult. Nick spent the long cold, wet winter nights of 2013/14 gathering data from around the harbour and in his completed report discovered there were quite a few more than first thought!

Trends in Nightjar, Woodlark and Dartford Warbler on Dorset Heaths from 1991 – 2013

In early 2014 a report was commissioned to identify the trends of three of Dorset’s most important heathland species. The report was commisioned by Birds of Poole Harbour and carried out by Footprint Ecology who have kindly supplied us with the final report to put on our website.

This report summarises data on nightjar Caprimulgus europaeus, woodlark Lullula arborea and Dartford warbler Sylvia undata across the Dorset Heaths. These species are key features of the designated heathland sites and are ones for which the UK has an international responsibility. In this report we pool data from multiple sites and years to plot the overall trends for each species over the period 1991-2013. The results have implications for the long term monitoring of the birds on the Dorset Heaths and have implications for local conservation effort, planning policy and heathland management

Poole Harbour 2013 breeding Marsh Harriers

As you hopefully know by now, Poole Harbour hosted its first successful pair of breeding Marsh Harrier in 50 years this year with three young birds fledging the nest in August 2013. The nest was situated on private land at Swineham and was monitored on an almost daily basis by local Harrier expert and addict, Peter Hadrill from a distant viewpoint, providing a detailed picture into this historic event.

Peter has kindly allowed Birds of Poole Harbour to publish his day by day, month by month account which explains how these birds overcame unwelcomed visitors and an exceptionally cold spring.

The effects of bait harvesting on bird distribution and foraging in Poole Harbour SPA

Footprint Ecology was commissioned by Natural England to investigate whether there were any impacts of bait harvesting on bird behaviour in Poole Harbour. Aerial images of the harbour bays were captured by a drone plane and from these the extent and intensity of mud scarring was mapped and quantified. Time lapse cameras considered the distribution of birds in experimental plots (those dug for bait and a control) and direct observations and count of birds were undertaken to consider any effect on bird behaviours. Survey effort and recording was largely focussed on two parts of the Harbour: Arne Bay and Holes Bay

The final report is available by following the below link and clicking on the second report in the list.

Poole Harbour Water Rail Survey 2004 and 2013

Water Rail are a difficult species to see to due to their shy, timid nature not to mention their select choice of habitat, thick, dense reedbed. Back in 2003 it was thought that the whole UK population of Water Rail was somewhere between 400-900 pairs, but due to the numbers that could be heard ‘squealing’ and ‘sharming’ from Poole Harbour reed beds in the spring a survey was conducted to get an accurate picture of exactly how many pairs utilized this one area alone. The results were very interesting.

Ten years later a replica survey was conducted to see if there had been any shifts or changes in their numbers or distribution across the harbour.

Attached is the 2004 survey conducted by surveyor Dave Chown along with the more recent 2013 survey conducted by surveyor Nick Hopper and supported by Dave chown.

Gulls of Poole Harbour

In 2007 Mark Constantine commissioned a Waders and Waterfowl survey for Poole Harbour to run from January 2007 to February 2008. Part of the remit was to also record gull numbers and activities. At the end of the survey a dedicated gull survey was also commissioned for the whole of March 2008 to supplement findings, discover catchment areas used outside the harbour and assess numbers of birds using the harbour. 

For the first time you can now read the full and final report by Nick Hopper - co-author of The Sound Approachs 'Catching the Bug'
 
Waders and Waterfowl of Poole Harbour

In 2007/08 whilst co-writing the new Sound Approach title 'Catching the Bug', local surveyor and birder Nick Hopper was asked to do a repeat survey of D.R Collins 1984 survey that looked into Poole Harbour’s wader and waterfowl populations and distribution for BP (ltd) Development. The findings were used and published in the final edit of ‘Catching the Bug’, but for the first time ever you can now read Nick Hoppers full report that was finished in 2008.

Mediterranean and Black-headed Gull Census – May 2015

In early 2015 it was discussed and agreed that Birds of Poole Harbour would commission a full breeding gull census of the entire harbour. An important part of this census would included the established gull colonies on the islands off Holton Lee, set in the Wareham Channel. As described in this report, due to a natural set of circumstances, and perhaps some not so natural, the data collected from the islands wouldn’t be a true representation of the potential populations, so the census of the entire harbour was stopped.

This report looks at and discusses the Mediterranean and Black-headed Gull colonies on ‘Gull Islands’ in the Wareham Channel and the reasons behind the final totals.

Lytchett Bay Annual Reports

Lytchett Bay is in the north west of the harbour and is only a fraction smaller than it’s neighbor Holes Bay. The bay has a nice selection of habitats surrounding it, ranging from a small section of Dorset heathland, dense reedbed and grazed wetland. The site  has consistently been monitored and surveyed since 1992 by local birder Shaun Robson, who has built up a hugely detailed and accurate portrait of the areas birds and their habits. Below is each of his reports dating back to 2006, but we are currently aiming to get all reports dating back to 1992. Until then enjoy the below reports……
