Ages chart illustrates the age and gender trends across all age and gender groupings. A chart where the the covered area is primarily on the right describes a very young population while a chart where the the covered area is primarily on the left illustrates an aging population.

The 2014 Town and Community Profiles bring together information on more than 1000 Victorian communities from a wide variety of sources, both internal and external to the Department of Health and Department of Human Services. The Profiles include information on population, geography, services and facilities, and social, cultural and demographic characteristics of each suburb, town and rural catchment in Victoria.

Abstract: Since 1994, Ceredigion County Council and a network of shore-based volunteer observes have monitored levels of boat traffic and the occurrence of bottlenose dolphins at seven sites on the coast of Cardigan Bay, Wales. We report high rates of site use and site occupancy by this species during the summer. Although trends in site use may not reflect population trends in the wider region, these data were consistent with recent abundance estimates that indicate that the number of bottlenose dolphins using Cardigan Bay is stable or slightly increasing.

The conservation status of bottlenose dolphin (Tursiops truncatus) has been categorised by Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) as data deficient, indicating that inadequate information exists for this species concerning its distribution and population status. The only two areas in UK waters that have been identified as having the physical and biological factors essential to the life and reproduction of a population of bottlenose dolphins Tursiops truncatus are Cardigan Bay, Wales and the Moray Firth, Scotland. The bottlenose dolphin Tursiops truncatus population of Cardigan Bay off the west coast of Wales has been estimated to consist of around 125 individuals. The dolphins appear to use the inshore waters of Cardigan Bay for both feeding and reproduction, and in the summer months calves and juveniles are often observed with adult individuals or groups. The dataset contains photographic images of cetaceans from Cardigan Bay, Pwllheli and Fishguard. This photo-identification catalogue consists of an identification sheet for each bottlenose dolphin that has been successfully identified by volunteer researchers at Cardigan Bay Marine Wildlife Centre. The recognition of individual bottlenose dolphin is essential to the studies associated with animal behaviour and ecology. Photo-identification was conducted to create a permanent record of bottlenose dolphins encountered around Cardigan Bay and facilitate in the identification of individual bottlenose dolphins as an individual, enabling future identification.

A population of bottlenose dolphins forms a primary interest of Cardigan Bay and it was for this that Cardigan Bay was first selected as a Special Area of Conservation (SAC). Cardigan Bay is known to host the largest population of semi-resident bottlenose dolphins in the UK. The data collected as part of this research is being used to monitor the population dynamics and behaviour of bottlenose dolphins and harbour porpoises in Cardigan Bay. Cardigan Bay is known to host the largest population of semi-resident bottlenose dolphins in the UK. This data covers monitoring carried out by the Sea Watch Foundation between 2011-2013 on behalf of the Countryside Council for Wales (CCW) and subsequently Natural Resources Wales (NRW), to monitor bottlenose dolphin and harbour porpoise populations in Cardigan Bay. The goal of this data collection was to monitor bottlenose dolphin and harbour porpoise populations in Cardigan Bay. The aims were to: - Provide information on the condition of bottlenose dolphins and harbour porpoises in Cardigan Bay including Cardigan Bay and Pen Llyn a'r Sarnau Special Areas of Conservation; - To use photo-identification techniques to evaluate dolphin movements distribution and abundance; - To assess supporting habitats.

The marine red alga Anotrichium barbatum is one of two rare seaweeds in the UK with a Species Action Plan. The alga was detected in Tremadog Bay in 1998. The site was resurveyed in 1999 and Anotrichium barbatum was again recorded. The dataset contains information on the geographical distribution of the alga and density estimates. In 1997 an Action Plan was prepared for English Nature, but downgraded to a Species Statement because there were no known extant UK populations. The discovery of Anotrichium barbatum in Cardigan Bay in 1998 permitted the completion in 1998 of the Action Plan with target. The minimum objective is to stabilize the species' status i.e. to maintain the net population size and distribution against baseline figures set at the time of Action Plan publication.
