Vật dụng làm giàu môi trường ở đây.

Vật dụng means a practical object, item, or piece of equipment used for some purpose.

In this sentence, it most likely means items used for environmental enrichment.

By itself, vật dụng does not clearly mark singular or plural. Vietnamese often leaves that to context.

• vật dụng = item/items
• một vật dụng = one item
• các vật dụng or những vật dụng = items, several items

So the sentence could refer to one item, several items, or even a category label, depending on the situation.

Literally, làm giàu môi trường means to make the environment richer.

But in real use, especially in animal care, zoos, education, or therapy contexts, it usually means environmental enrichment: adding things that make an environment more stimulating, interesting, or beneficial.

So in this sentence, vật dụng làm giàu môi trường means something like:

• items for environmental enrichment
• environmental enrichment items
• objects used to enrich the environment

It is a more specialized expression than the literal English words might suggest.

Because Vietnamese often does not use a copula in the same way English does.

In a sentence like this, ở đây acts as the predicate meaning is here / are here.

So:

• Vật dụng làm giàu môi trường ở đây = The environmental enrichment items are here

You do not normally use là before a location.

• natural: Vật dụng làm giàu môi trường ở đây
• unnatural: Vật dụng làm giàu môi trường là ở đây

Use là mainly for identification or equivalence, not simple location.

The structure is:

• Vật dụng = item(s)
• làm giàu môi trường = that enrich the environment / for enriching the environment
• ở đây = here

So the sentence is basically:

• [noun phrase] + [location]

More literally, the order is:

• items for environmental enrichment + here

This is normal Vietnamese word order. The main noun comes first, and descriptive material often follows it.

Because Vietnamese usually puts the main noun first and then adds descriptive information after it.

So:

• vật dụng làm giàu môi trường = items that are used to enrich the environment

This is the opposite of English in many cases. English often puts modifiers before the noun, but Vietnamese often places them after the noun.

Compare:

• English: environmental enrichment items
• Vietnamese: vật dụng làm giàu môi trường

The Vietnamese version is closer to items for enriching the environment.

It could be there, but it does not have to be.

Both are understandable:

• vật dụng làm giàu môi trường
• vật dụng để làm giàu môi trường

The version with để is more explicit and clearly means items used in order to enrich the environment.

The version without để is shorter and more compact, which is common in labels, headings, and concise descriptions.

So:

• with để = more explicit
• without để = more compact, often more label-like

Ở đây means here, in this place, or sometimes in this section/area, depending on context.

It can refer to:

• a physical place: here in this room, here on this table
• a section of a display or sign: here in this part
• a point in a conversation or text: here, at this point

So if this sentence appears on a sign, ở đây may simply mean the enrichment items are located here.

It can work as a sentence, but it has a somewhat label-like or sign-like feel.

That is because it is short, compact, and matter-of-fact.

Depending on context, a speaker might also say:

• Các vật dụng làm giàu môi trường ở đây.
  More clearly plural

• Vật dụng làm giàu môi trường ở đây nhé.
  More conversational

• Đây là vật dụng làm giàu môi trường.
  This means This is an environmental enrichment item, which is a different structure

So the original sentence is natural, especially for signage, labeling, or brief explanation.

To make it clearer, you can add words that show number:

• Một vật dụng làm giàu môi trường ở đây.
  One environmental enrichment item is here

• Các vật dụng làm giàu môi trường ở đây.
  The environmental enrichment items are here

• Những vật dụng làm giàu môi trường ở đây.
  Environmental enrichment items are here / those items are here

Vietnamese often leaves number unstated unless it matters, so the original sentence is normal even without this information.

Yes, but the nuance changes a little.

• vật dụng: neutral, fairly formal, practical items
• đồ dùng: everyday-use items, more common and ordinary
• dụng cụ: tools or instruments, often more specifically functional

So:

• vật dụng làm giàu môi trường sounds neutral and suitable for formal description
• đồ dùng làm giàu môi trường sounds a bit more everyday
• dụng cụ làm giàu môi trường may sound more like tools or apparatus

Which one is best depends on what the objects actually are. If they are general enrichment objects, vật dụng is a good choice.
