Garden Helpers: Little creatures, big helpers

Little creatures that help in a big way

The major helpers in the garden all reside within the soil community. The hardest and most efficient workers are the smallest; bacteria and fungi, which decompose organic material. The larger helpers are the toads, lizards and birds that catch and eat other pests, although, birds might eat your fruits as well.

So here is a quick overview of the major kingdoms within which most organisms are divided into.

Garden Helpers Taxonomic Classification of Life, Animals, Plants, Fungi, Protokaryota

Please people, not all arthropods or bacteria are bugs! Bugs (Hemiptera) are one of the major classes within the insect phylum. Also not all bacteria are germs, 70-80% of all bacteria and fungi are beneficial, the same goes for most insects.

The unseen workers are the bacteria, small fungi (yeasts and mould) and nematodes, as these are microscopic. Therefore I will discuss the larger creatures of the garden: Arthropods, Annelids, Molluscs, Amphibians, Reptiles and Birds.



  • Annelids

These are segmented invertebrates, known as ‘True worms’. They inhabit marine, freshwater and soil environments. Earthworms, bristle worms and leeches occupy this phylum.


Pink squashy things. I do not perceive earthworms as gross, even before I had the wormery, so I never understand why the majority of people pull faces at the sight of them. There are far more disgusting things in our world (those microscopic and parasitic organisms we work with in biological laboratories ). I always associate them with that funny childhood character EarthWorm Jim – the superhero-spacesuit-wearing-earthworm… Earthworms are responsible for the decomposition of large items, after which the bacteria and fungi do the rest of the work. You can check out my Wormery – VermiCompost post here!

  • Molluscs

Soft bodied invertebrates that are mostly marine and freshwater inhabitants. Slugs and snails are the important ones to gardeners, as they are mostly pests. I do not have a problem with either, probably as we are not so ‘urbanised’ as most cities, so a lot of their predators are around – I think it is too dry here also for them to get out of hand… I did keep freshwater golden apple snails for a while – one of the best pets ever, low maintenance and fun to watch!

  • Arthropods

Arthropods are invertebrates with an external skeleton and jointed body parts. Arthropods are the largest group of diverse organisms in the animal kingdom.


This class consists of predators (spiders, scorpions, harvestmen) and parasites (mites and ticks). Our garden has a large Strelitzia (bird of paradise plant) that houses all types of spider crawlies, usually tent spiders and lots of jumping spiders. There isn’t much else to discuss about spiders as I assume most of us are well associated with them as they hunt down all the pests in the garden.

  • Crustaceans

Mainly an aquatic class of invertebrates with jaws and one pair of antennae. Crustaceans in the garden are woodlice (not really a louse, true lice are grouped with the insects) and other decomposing crustaceans such as the ones I have in the wormery.

  • Insects

Insects are the largest animal group in terms of numbers and diversity, especially when it comes to mouth parts and adaptability. Insects are the easiest to recognise and the most abundant in the garden. They are decomposers, pollinators, predators and parasites – basically a whole National Geographic episode in miniature!

  • Amphibia


These vertebrates have moist scaleless skin and can be found in freshwater and on the land. Frogs generally are water-bound (some tree frogs stay in very moist environments away from water) and toads are landlubbers. If you have a pond, the frogs shall move in and act as predators to all the larger pest-insects of the garden, such as crickets and grasshoppers. Toads like a moist and shady environment. Fred, the toad (or rather toads) who make the garden their nursery and patrol it at night for juicy morsels…

  • Reptilia


Almost opposites of amphibians, with dry, scaly skin. They include small and large lizards, turtles, crocodiles, snakes and tortoises. Skinks and smaller lizards will roam the garden for insect to gobble and if you garden offers a lot of nice lizard hideouts they’ll be on permanent  pest eradication duty. A tortoise was roaming about the lawn once. Don’t think it was a pet, so it just passed on through to the bushveld.

  • Aves


Feathered vertebrates and capable of flight (FYI – feathers first evolved as insulation in dinosaur-like-birds, and not for fight, which was a secondary benefit after some millions of years). Birds can act as predators, eating insects (even aphids, yeah!), or pollinators, when visiting flowers for nectar. I do not enlist the help of birds in my garden, as they will likely eat everything else (becoming a pest rather than a helper), luckily my garden is next to the cat walkway.
