Choosing a topic for study
The first stage of a research project is choosing a subject area in which to research (see Box 1.1 for a list of some texts that include ecological project ideas). As you will be devoting substantial time to your project, it is important to choose a topic that interests you. You may also wish to make your research relevant to your current or future employment. A variety of organisations – local, national, and international – may be able to help you identify an area of interest that is also of current relevance. Such organisations include local authorities and wildlife trusts, nature reserves, museums, and (inter)national bodies such as the RSPB, Plantlife, and WWF (Naturenet provides a list of some such organisations that may be able to help).1 Pick a topic of the right size: neither too big nor too small – typically the fieldwork component of most undergraduate projects are less than 6 weeks in length. Looking at successful previous projects may assist you in judging how much can be done in the available time (ask more experienced researchers for examples of good projects to look at). Finally, your proposed project has to be feasible; for example, in terms of equipment, access to sites, and realistic timescales. Once you have selected your subject and provisional title, be prepared to be flexible and, if necessary, to change direction. This may happen for a variety of reasons; for example, if a pilot study reveals a more interesting avenue for research, or if your original ideas turn out to be unfeasible. You should note that the planning process should involve a consideration of the whole project to enable you to identify and deal with any potential problems before they become major issues (see Figure 1.1). In all aspects, reading around the subject will allow you to use appropriate techniques, build on existing knowledge, and avoid reinventing the wheel. Inevitably, there can be logistical problems that influence your choice of site, or species, or otherwise prevent you from proceeding exactly as you would have wished. Although you can avoid many such problems by careful planning, there are some aspects that you will not think about until you implement the research. A pilot study will help to identify such issues and may allow you to refine the study in advance of full implementation. If you are unable to do a pilot study, at least try to explain your approach to someone who has spent time doing ecological fieldwork. They may highlight some obvious deficiencies. This is particularly useful for field trips abroad, which preclude a pilot and can be fraught with difficulty.

Box 1.1 Some sources of ecology projects
There are a number of journal papers that list topics of interest in ecology and associated fields (e.g. Sutherland et al. 2006; Sutherland et al. 2009; Pretty et al. 2010; Sutherland et al. 2013). Even if the projects themselves are not of direct interest, they may inspire other project work since there is plenty of debate stemming from these papers on a variety of blogs and forums.
Natural England has a list of research ideas on their national nature reserves https://www.gov.uk/government/publications/research-opportunities-on-national-nature-reserves-in-england
There are many other resources that give examples of feasible ecological research projects. The series listed below are examples of some of those that cover either a wide range of habitat types, or a range of organisms.
The Practical Ecology Series provide project ideas associated with grasslands (Brodie 1985), freshwaters (Gee 1986), the seashore (Jenkins 1983), and urban areas (Smith 1984).
Routledge Habitat Guides each include a section (section 5) giving project ideas for the habitats associated with grasslands (Price 2003), uplands (Fielding and Howarth 1999), urban habitats (Wheater 1999), and woodlands (Read and Frater 1999).
The Biology of Habitats Series covers a wide range of global habitat types and includes practical aspects of working within the habitat and some of the types of studies that are possible within them (e.g. Rydin and Jeglum 2013 for peatlands and Little et al. 2009 for rocky shores).
The Naturalists' Handbook Series (now published by Pelagic Publishing) contains many ideas related to studying a group of species (e.g. Gilbert 2015 on hoverflies or Roy et al. 2013 on ladybirds), or different habitats (e.g. Hayward 2015 on sandy shores or Wheater and Read 1996 on animals under logs and stones), or implementing different techniques (e.g. Unwin and Corbet 1991 look at insects and microclimate, whilst Richardson 1992 examines pollution monitoring using lichens).
Ecological research questions
Having decided on a provisional topic, the next step in the successful planning of any research project is to identify those questions you wish to ask and then to formulate the aims and objectives. There are various reasons for researching particular plants, animals, or environments and this section provides a quick overview of the scope of ecological projects.
Many studies involve monitoring the number of species, number of individuals (relative abundance), estimates of population size or density (absolute abundance), or community structure (diversity, evenness, and richness). Additionally, studies on animals may require observations of the behaviour of individuals or groups and their interactions with each other and their environment.
Monitoring individual species and groups of species
Sometimes, projects may be targeted at a single species (i.e. an autecological study). For example, where a species is judged to be important for positive reasons (including its conservation or commercial value) you might require information about its distribution, population size and dynamics, age structure, behaviour,
